Svelte MultiSelect

Keyboard-friendly, accessible and highly customizable multi-select component. View the docs

💡 Features

Bindable: bind:selected gives you an array of the currently selected options. Thanks to Svelte's 2-way binding, it can also control the component state externally through assignment selected = ['foo', 42].
Keyboard friendly for mouse-less form completion
No run-time deps: needs only Svelte as dev dependency
Dropdowns: scrollable lists for large numbers of options
Searchable: start typing to filter options
Tagging: selected options are listed as tags within the input
Single / multiple select: pass maxSelect={1, 2, 3, ...} prop to restrict the number of selectable options
Configurable: see props

📜 Breaking changes

8.0.0 (2022-10-22)
- Props selectedLabels and selectedValues were removed. If you were using them, they were equivalent to assigning bind:selected to a local variable and then running selectedLabels = selected.map(option => option.label) and selectedValues = selected.map(option => option.value) if your options were objects with label and value keys. If they were simple strings/numbers, there was no point in using selected{Labels,Values} anyway. PR 138
- Prop noOptionsMsg was renamed to noMatchingOptionsMsg. PR 133.
v8.3.0 (2023-01-25) addOptionMsg was renamed to createOptionMsg (no major since version since it's rarely used) sha.
v9.0.0 (2023-06-01) Svelte bumped from v3 to v4. Also, not breaking but noteworthy: MultiSelect received a default slot that functions as both "option" and "selected". If you previously had two identical slots for "option" and "selected", you can now remove the name from one of them and drop the other:
```
<MultiSelect
  {options}
+ let:option
>
- <SlotComponent let:option {option} slot="selected" />
- <SlotComponent let:option {option} slot="option" />
+ <SlotComponent {option} />
</MultiSelect>
```
v10.0.0 (2023-06-23) duplicateFunc() renamed to key in #238. Signature changed:
```
- duplicateFunc: (op1: T, op2: T) => boolean = (op1, op2) => `${get_label(op1)}`.toLowerCase() === `${get_label(op2)}`.toLowerCase()
+ key: (opt: T) => unknown = (opt) => `${get_label(opt)}`.toLowerCase()
```
Rather than implementing custom equality in duplicateFunc, the key function is now expected to map options to a unique identifier. key(op1) === key(op2) should mean op1 and op2 are the same option. key can return any type but usually best to return primitives (string, number, ...) for Svelte keyed each blocks (see #217).

🔣 Props

Full list of props/bindable variables for this component. The Option type you see below is defined in src/lib/index.ts and can be imported as import { type Option } from 'svelte-multiselect'.

```
activeIndex: number | null = null
```
Zero-based index of currently active option in the array of currently matching options, i.e. if the user typed a search string into the input and only a subset of options match, this index refers to the array position of the matching subset of options
```
activeOption: Option | null = null
```
Currently active option, i.e. the one the user currently hovers or navigated to with arrow keys.
```
createOptionMsg: string | null = `Create this option...`
```
The message shown to users when allowUserOptions is truthy and they entered text that doesn't match any existing options to suggest creating a new option from the entered text. Emits console.error if allowUserOptions is true or 'append' and createOptionMsg='' to since users might be unaware they can create new option. The error can be silenced by setting createOptionMsg=null indicating developer intent is to e.g. use MultiSelect as a tagging component where a user message might be unwanted.
```
allowEmpty: boolean = false
```
Whether to console.error if dropdown list of options is empty. allowEmpty={false} will suppress errors. allowEmpty={true} will report a console error if component is not disabled, not in loading state and doesn't allowUserOptions.
```
allowUserOptions: boolean | 'append' = false
```
Whether users can enter values that are not in the dropdown list. true means add user-defined options to the selected list only, 'append' means add to both options and selected. If allowUserOptions is true or 'append' then the type object | number | string of entered value is determined by typeof options[0] (i.e. the first option in the dropdown list) to keep type homogeneity.
```
autocomplete: string = `off`
```
Applied to the <input>. Specifies if browser is permitted to auto-fill this form field. Should usually be one of 'on' or 'off' but see MDN docs for other admissible values.
```
autoScroll: boolean = true
```
false disables keeping the active dropdown items in view when going up/down the list of options with arrow keys.
```
breakpoint: number = 800
```
Screens wider than breakpoint in pixels will be considered 'desktop', everything narrower as 'mobile'.
```
defaultDisabledTitle: string = `This option is disabled`
```
Title text to display when user hovers over a disabled option. Each option can override this through its disabledTitle attribute.
```
disabled: boolean = false
```
Disable the component. It will still be rendered but users won't be able to interact with it.
```
disabledInputTitle: string = `This input is disabled`
```
Tooltip text to display on hover when the component is in disabled state.
```
duplicates: boolean = false
```
Whether to allow users to select duplicate options. Applies only to the selected item list, not the options dropdown. Keeping that free of duplicates is left to developer. The selected item list can have duplicates if allowUserOptions is truthy, duplicates is true and users create the same option multiple times. Use duplicateOptionMsg to customize the message shown to user if duplicates is false and users attempt this and key to customize when a pair of options is considered equal.
```
duplicateOptionMsg: string = `This option is already selected`
```
Text to display to users when allowUserOptions is truthy and they try to create a new option that's already selected.

```
key: (opt: T) => unknown = (opt) => `${get_label(opt)}`.toLowerCase()
```
A function that maps options to a value by which equality of options is determined. Defaults to mapping options to their lower-cased label. E.g. by default const opt1 = { label: `foo`, id: 1 } and const opt2 = { label: `foo`, id: 2 } are considered equal. If you want to consider them different, you can set key to e.g. key={(opt) => opt.id} or key={(opt) => `${opt.label}-${opt.id}} or even key={JSON.stringify}.

filterFunc = (opt: Option, searchText: string): boolean => {
  if (!searchText) return true
  return `${get_label(opt)}`.toLowerCase().includes(searchText.toLowerCase())
}

Customize how dropdown options are filtered when user enters search string into <MultiSelect />. Defaults to:

```
closeDropdownOnSelect: boolean | 'desktop' = `desktop`
```
One of true, false or 'desktop'. Whether to close the dropdown list after selecting a dropdown item. If true, component will loose focus and dropdown is closed. 'desktop' means false if current window width is larger than the current value of breakpoint prop (default is 800, meaning screen width in pixels). This is to align with the default behavior of many mobile browsers like Safari which close dropdowns after selecting an option while desktop browsers facilitate multi-selection by leaving dropdowns open.
```
form_input: HTMLInputElement | null = null
```
Handle to the <input> DOM node that's responsible for form validity checks and passing selected options to form submission handlers. Only available after component mounts (null before then).
```
highlightMatches: boolean = true
```
Whether to highlight text in the dropdown options that matches the current user-entered search query. Uses the CSS Custom Highlight API with limited browser support (70% as of May 2023) and styling options. See ::highlight(sms-search-matches) below for available CSS variables.
```
id: string | null = null
```
Applied to the <input> element for associating HTML form <label>s with this component for accessibility. Also, clicking a <label> with same for attribute as id will focus this component.
```
input: HTMLInputElement | null = null
```
Handle to the <input> DOM node. Only available after component mounts (null before then).
```
inputmode: string | null = null
```
The inputmode attribute hints at the type of data the user may enter. Values like 'numeric' | 'tel' | 'email' allow mobile browsers to display an appropriate virtual on-screen keyboard. See MDN for details. If you want to suppress the on-screen keyboard to leave full-screen real estate for the dropdown list of options, set inputmode="none".
```
inputStyle: string | null = null
```
One-off CSS rules applied to the <input> element.
```
invalid: boolean = false
```
If required = true, 1, 2, ... and user tries to submit form but selected = [] is empty/selected.length < required, invalid is automatically set to true and CSS class invalid applied to the top-level div.multiselect. invalid class is removed as soon as any change to selected is registered. invalid can also be controlled externally by binding to it <MultiSelect bind:invalid /> and setting it to true based on outside events or custom validation.
```
liOptionStyle: string | null = null
```
One-off CSS rules applied to the <li> elements that wrap the dropdown options.
```
liSelectedStyle: string | null = null
```
One-off CSS rules applied to the <li> elements that wrap the selected options.
```
loading: boolean = false
```
Whether the component should display a spinner to indicate it's in loading state. Use <slot name='spinner'> to specify a custom spinner.
```
matchingOptions: Option[] = []
```
List of options currently displayed to the user. Same as options unless the user entered searchText in which case this array contains only those options for which filterFunc = (op: Option, searchText: string) => boolean returned true.
```
maxOptions: number | undefined = undefined
```
Positive integer to limit the number of options displayed in the dropdown. undefined and 0 mean no limit.
```
maxSelect: number | null = null
```
Positive integer to limit the number of options users can pick. null means no limit. maxSelect={1} will change the type of selected to be a single Option (or null) (not a length-1 array). Likewise, the type of selectedLabels changes from (string | number)[] to string | number | null and selectedValues from unknown[] to unknown | null. maxSelect={1} will also give div.multiselect a class of single. I.e. you can target the selector div.multiselect.single to give single selects a different appearance from multi selects.
```
maxSelectMsg: ((current: number, max: number) => string) | null = (
  current: number,
  max: number
) => (max > 1 ? `${current}/${max}` : ``)
```
Inform users how many of the maximum allowed options they have already selected. Set maxSelectMsg={null} to not show a message. Defaults to null when maxSelect={1} or maxSelect={null}. Else if maxSelect > 1, defaults to:
```
maxSelectMsg = (current: number, max: number) => `${current}/${max}`
```
Use CSS selector span.max-select-msg (or prop maxSelectMsgClass if you're using a CSS framework like Tailwind) to customize appearance of the message container.
```
minSelect: number | null = null
```
Conditionally render the x button which removes a selected option depending on the number of selected options. Meaning all remove buttons disappear if selected.length <= minSelect. E.g. if 2 options are selected and minSelect={3}, users will not be able to remove any selections until they selected more than 3 options.

Note: Prop required={3} should be used instead if you only care about the component state at form submission time. minSelect={3} should be used if you want to place constraints on component state at all times.
```
name: string | null = null
```
Applied to the <input> element. Sets the key of this field in a submitted form data object. See form example.
```
noMatchingOptionsMsg: string = `No matching options`
```
What message to show if no options match the user-entered search string.
```
open: boolean = false
```
Whether the dropdown list is currently visible. Is two-way bindable, i.e. can be used for external control of when the options are visible.
```
options: Option[]
```
The only required prop (no default). Array of strings/numbers or Option objects to be listed in the dropdown. The only required key on objects is label which must also be unique. An object's value defaults to label if undefined. You can add arbitrary additional keys to your option objects. A few keys like preselected and title have special meaning though. See type ObjectOption in /src/lib/types.ts for all special keys and their purpose.
```
outerDiv: HTMLDivElement | null = null
```
Handle to outer <div class="multiselect"> that wraps the whole component. Only available after component mounts (null before then).
```
parseLabelsAsHtml: boolean = false
```
Whether option labels should be passed to Svelte's @html directive or inserted into the DOM as plain text. true will raise an error if allowUserOptions is also truthy as it makes your site susceptible to cross-site scripting (XSS) attacks.
```
pattern: string | null = null
```
The pattern attribute specifies a regular expression which the input's value must match. If a non-null value doesn't match the pattern regex, the read-only patternMismatch property will be true. See MDN for details.
```
placeholder: string | null = null
```
String shown in the text input when no option is selected.
```
removeAllTitle: string = `Remove all`
```
Title text to display when user hovers over remove-all button.
```
removeBtnTitle: string = `Remove`
```
Title text to display when user hovers over button to remove selected option (which defaults to a cross icon).
```
required: boolean | number = false
```
If required = true, 1, 2, ... forms can't be submitted without selecting given number of options. true means 1. false means even empty MultiSelect will pass form validity check. If user tries to submit a form containing MultiSelect with less than the required number of options, submission is aborted, MultiSelect scrolls into view and shows message "Please select at least required options".
```
resetFilterOnAdd: boolean = true
```
Whether text entered into the input to filter options in the dropdown list is reset to empty string when user selects an option.
```
searchText: string = ``
```
Text the user-entered to filter down on the list of options. Binds both ways, i.e. can also be used to set the input text.
```
selected: Option[] =
 options
   ?.filter((op) => (op as ObjectOption)?.preselected)
   .slice(0, maxSelect ?? undefined) ?? []
```
Array of currently selected options. Supports 2-way binding bind:selected={[1, 2, 3]} to control component state externally. Can be passed as prop to set pre-selected options that will already be populated when component mounts before any user interaction.
```
sortSelected: boolean | ((op1: Option, op2: Option) => number) = false
```
Default behavior is to render selected items in the order they were chosen. sortSelected={true} uses default JS array sorting. A compare function enables custom logic for sorting selected options. See the /sort-selected example.
```
selectedOptionsDraggable: boolean = !sortSelected
```
Whether selected options are draggable so users can change their order.
```
style: string | null = null
```
One-off CSS rules applied to the outer <div class="multiselect"> that wraps the whole component for passing one-off CSS.
```
ulSelectedStyle: string | null = null
```
One-off CSS rules applied to the <ul class="selected"> that wraps the list of selected options.
```
ulOptionsStyle: string | null = null
```
One-off CSS rules applied to the <ul class="options"> that wraps the list of selected options.
```
value: Option | Option[] | null = null
```
If maxSelect={1}, value will be the single item in selected (or null if selected is empty). If maxSelect != 1, maxSelect and selected are equal. Warning: Setting value does not rendered state on initial mount, meaning bind:value will update local variable value whenever internal component state changes but passing a value when component first mounts won't be reflected in UI. This is because the source of truth for rendering is bind:selected. selected is reactive to value internally but only on reassignment from initial value. Suggestions for better solutions than #249 welcome!

🎰 Slots

MultiSelect.svelte accepts the following named slots:

slot="option": Customize rendering of dropdown options. Receives as props an option and the zero-indexed position (idx) it has in the dropdown.
slot="selected": Customize rendering of selected items. Receives as props an option and the zero-indexed position (idx) it has in the list of selected items.
slot="spinner": Custom spinner component to display when in loading state. Receives no props.
slot="disabled-icon": Custom icon to display inside the input when in disabled state. Receives no props. Use an empty <span slot="disabled-icon" /> or div to remove the default disabled icon.
slot="expand-icon": Allows setting a custom icon to indicate to users that the Multiselect text input field is expandable into a dropdown list. Receives prop open: boolean which is true if the Multiselect dropdown is visible and false if it's hidden.
slot="remove-icon": Custom icon to display as remove button. Will be used both by buttons to remove individual selected options and the 'remove all' button that clears all options at once. Receives no props.
slot="user-msg": Displayed like a dropdown item when the list is empty and user is allowed to create custom options based on text input (or if the user's text input clashes with an existing option). Receives props:
- searchText: The text user typed into search input.
- msgType: false | 'create' | 'dupe' | 'no-match': 'dupe' means user input is a duplicate of an existing option. 'create' means user is allowed to convert their input into a new option not previously in the dropdown. 'no-match' means user input doesn't match any dropdown items and users are not allowed to create new options. false means none of the above.
- msg: Will be duplicateOptionMsg or createOptionMsg (see props) based on whether user input is a duplicate or can be created as new option. Note this slot replaces the default UI for displaying these messages so the slot needs to render them instead (unless purposely not showing a message).
slot='after-input': Placed after the search input. For arbitrary content like icons or temporary messages. Receives props selected: Option[], disabled: boolean, invalid: boolean, id: string | null, placeholder: string, open: boolean, required: boolean. Can serve as a more dynamic, more customizable alternative to the placeholder prop.

Example using several slots:

<MultiSelect options={[`Red`, `Green`, `Blue`, `Yellow`, `Purple`]} let:idx let:option>
   <!-- default slot overrides rendering of both dropdown-listed and selected options -->
  <span>
    {idx + 1}
    {option.label}
    <span style:background={option.label} style=" width: 1em; height: 1em;" />
  </span>

  <CustomSpinner slot="spinner">
  <strong slot="remove-icon">X</strong>
</MultiSelect>

🎬 Events

MultiSelect.svelte dispatches the following events:

```
on:add={(event) => console.log(event.detail.option)}
```
Triggers when a new option is selected. The newly selected option is provided as event.detail.option.
```
on:remove={(event) => console.log(event.detail.option)}`
```
Triggers when a single selected option is removed. The removed option is provided as event.detail.option.
```
on:removeAll={(event) => console.log(event.detail.options)}`
```
Triggers when all selected options are removed. The payload event.detail.options gives the options that were previously selected.
```
on:change={(event) => console.log(`${event.detail.type}: '${event.detail.option}'`)}
```
Triggers when an option is either added (selected) or removed from selected, or all selected options are removed at once. type is one of 'add' | 'remove' | 'removeAll' and payload will be option: Option or options: Option[], respectively.
```
on:open={(event) => console.log(`Multiselect dropdown was opened by ${event}`)}
```
Triggers when the dropdown list of options appears. Event is the DOM's FocusEvent,KeyboardEvent or ClickEvent that initiated this Svelte dispatch event.
```
on:close={(event) => console.log(`Multiselect dropdown was closed by ${event}`)}
```
Triggers when the dropdown list of options disappears. Event is the DOM's FocusEvent, KeyboardEvent or ClickEvent that initiated this Svelte dispatch event.

For example, here's how you might annoy your users with an alert every time one or more options are added or removed:

<MultiSelect
  on:change={(e) => {
    if (e.detail.type === 'add') alert(`You added ${e.detail.option}`)
    if (e.detail.type === 'remove') alert(`You removed ${e.detail.option}`)
    if (e.detail.type === 'removeAll') alert(`You removed ${e.detail.options}`)
  }}
/>

Note: Depending on the data passed to the component the options(s) payload will either be objects or simple strings/numbers.

The above list of events are Svelte dispatch events. This component also forwards many DOM events from the <input> node: blur, change, click, keydown, keyup, mousedown, mouseenter, mouseleave, touchcancel, touchend, touchmove, touchstart. Registering listeners for these events works the same:

<MultiSelect
  options={[1, 2, 3]}
  on:keyup={(event) => console.log('key', event.target.value)}
/>

🦺 TypeScript

The type of options is inferred automatically from the data you pass. E.g.

const options = [
   { label: `foo`, value: 42 }
   { label: `bar`, value: 69 }
]
// type Option = { label: string, value: number }
const options = [`foo`, `bar`]
// type Option = string
const options = [42, 69]
// type Option = number

The inferred type of Option is used to enforce type-safety on derived props like selected as well as slot components. E.g. you'll get an error when trying to use a slot component that expects a string if your options are objects (see this comment for example screenshots).

You can also import the types this component uses for downstream applications:

import {
  Option,
  ObjectOption,
  DispatchEvents,
  MultiSelectEvents,
} from 'svelte-multiselect'

✨ Styling

There are 3 ways to style this component. To understand which options do what, it helps to keep in mind this simplified DOM structure of the component:

<div class="multiselect">
  <ul class="selected">
    <li>Selected 1</li>
    <li>Selected 2</li>
  </ul>
  <ul class="options">
    <li>Option 1</li>
    <li>Option 2</li>
  </ul>
</div>

With CSS variables

If you only want to make small adjustments, you can pass the following CSS variables directly to the component as props or define them in a :global() CSS context. See app.css for how these variables are set on the demo site of this component.

Minimal example that changes the background color of the options dropdown:

<MultiSelect --sms-options-bg="white" />

div.multiselect
- border: var(--sms-border, 1pt solid lightgray): Change this to e.g. to 1px solid red to indicate this form field is in an invalid state.
- border-radius: var(--sms-border-radius, 3pt)
- padding: var(--sms-padding, 0 3pt)
- background: var(--sms-bg)
- color: var(--sms-text-color)
- min-height: var(--sms-min-height, 22pt)
- width: var(--sms-width)
- max-width: var(--sms-max-width)
- margin: var(--sms-margin)
- font-size: var(--sms-font-size, inherit)
div.multiselect.open
- z-index: var(--sms-open-z-index, 4): Increase this if needed to ensure the dropdown list is displayed atop all other page elements.
div.multiselect:focus-within
- border: var(--sms-focus-border, 1pt solid var(--sms-active-color, cornflowerblue)): Border when component has focus. Defaults to --sms-active-color which in turn defaults to cornflowerblue.
div.multiselect.disabled
- background: var(--sms-disabled-bg, lightgray): Background when in disabled state.
div.multiselect input::placeholder
- color: var(--sms-placeholder-color)
- opacity: var(--sms-placeholder-opacity)
div.multiselect > ul.selected > li
- background: var(--sms-selected-bg, rgba(0, 0, 0, 0.15)): Background of selected options.
- padding: var(--sms-selected-li-padding, 1pt 5pt): Height of selected options.
- color: var(--sms-selected-text-color, var(--sms-text-color)): Text color for selected options.
ul.selected > li button:hover, button.remove-all:hover, button:focus
- color: var(--sms-remove-btn-hover-color, lightskyblue): Color of the remove-icon buttons for removing all or individual selected options when in :focus or :hover state.
- background: var(--sms-remove-btn-hover-bg, rgba(0, 0, 0, 0.2)): Background for hovered remove buttons.
div.multiselect > ul.options
- background: var(--sms-options-bg, white): Background of dropdown list.
- max-height: var(--sms-options-max-height, 50vh): Maximum height of options dropdown.
- overscroll-behavior: var(--sms-options-overscroll, none): Whether scroll events bubble to parent elements when reaching the top/bottom of the options dropdown. See MDN.
- box-shadow: var(--sms-options-shadow, 0 0 14pt -8pt black): Box shadow of dropdown list.
- border: var(--sms-options-border)
- border-width: var(--sms-options-border-width)
- border-radius: var(--sms-options-border-radius, 1ex)
- padding: var(--sms-options-padding)
- margin: var(--sms-options-margin, inherit)
div.multiselect > ul.options > li
- scroll-margin: var(--sms-options-scroll-margin, 100px): Top/bottom margin to keep between dropdown list items and top/bottom screen edge when auto-scrolling list to keep items in view.
div.multiselect > ul.options > li.selected
- background: var(--sms-li-selected-bg): Background of selected list items in options pane.
- color: var(--sms-li-selected-color): Text color of selected list items in options pane.
div.multiselect > ul.options > li.active
- background: var(--sms-li-active-bg, var(--sms-active-color, rgba(0, 0, 0, 0.15))): Background of active options. Options in the dropdown list become active either by mouseover or by navigating to them with arrow keys. Selected options become active when selectedOptionsDraggable=true and an option is being dragged to a new position. Note the active option in that case is not the dragged option but the option under it whose place it will take on drag end.
div.multiselect > ul.options > li.disabled
- background: var(--sms-li-disabled-bg, #f5f5f6): Background of disabled options in the dropdown list.
- color: var(--sms-li-disabled-text, #b8b8b8): Text color of disabled option in the dropdown list.
::highlight(sms-search-matches): applies to search results in dropdown list that match the current search query if highlightMatches=true. These styles cannot be set via CSS variables. Instead, use a new rule set. For example:
```
::highlight(sms-search-matches) {
  color: orange;
  background: rgba(0, 0, 0, 0.15);
  text-decoration: underline;
}
```

With CSS frameworks

The second method allows you to pass in custom classes to the important DOM elements of this component to target them with frameworks like Tailwind CSS.

outerDivClass: wrapper div enclosing the whole component
ulSelectedClass: list of selected options
liSelectedClass: selected list items
ulOptionsClass: available options listed in the dropdown when component is in open state
liOptionClass: list items selectable from dropdown list
liActiveOptionClass: the currently active dropdown list item (i.e. hovered or navigated to with arrow keys)
liUserMsgClass: user message (last child of dropdown list when no options match user input)
liActiveUserMsgClass: user message when active (i.e. hovered or navigated to with arrow keys)
maxSelectMsgClass: small span towards the right end of the input field displaying to the user how many of the allowed number of options they've already selected

This simplified version of the DOM structure of the component shows where these classes are inserted:

<div class="multiselect {outerDivClass}">
  <input class={inputClass} />
  <ul class="selected {ulSelectedClass}">
    <li class={liSelectedClass}>Selected 1</li>
    <li class={liSelectedClass}>Selected 2</li>
  </ul>
  <span class="maxSelectMsgClass">2/5 selected</span>
  <ul class="options {ulOptionsClass}">
    <li class={liOptionClass}>Option 1</li>
    <li class="{liOptionClass} {liActiveOptionClass}">
      Option 2 (currently active)
    </li>
    ...
    <li class="{liUserMsgClass} {liActiveUserMsgClass}">
      Create this option...
    </li>
  </ul>
</div>

With global CSS

Odd as it may seem, you get the most fine-grained control over the styling of every part of this component by using the following :global() CSS selectors. ul.selected is the list of currently selected options rendered inside the component's input whereas ul.options is the list of available options that slides out when the component is in its open state. See also simplified DOM structure.

:global(div.multiselect) {
  /* top-level wrapper div */
}
:global(div.multiselect.open) {
  /* top-level wrapper div when dropdown open */
}
:global(div.multiselect.disabled) {
  /* top-level wrapper div when in disabled state */
}
:global(div.multiselect > ul.selected) {
  /* selected list */
}
:global(div.multiselect > ul.selected > li) {
  /* selected list items */
}
:global(div.multiselect button) {
  /* target all buttons in this component */
