This package has been deprecated in favour of the CA Design Systems Greedy Nav - please see Design System for details.
PriorityNav is a pure javascript plugin that will move your menu items if they don't fit its parent.
Take a look at the Demo site.
- Accessible
Adds appropriate aria attributes and set focus to links when needed. - No dependencies
The plugin is written in pure javascript making it fast and lean. - Breakpoint
When the breakpoint has been reached the plugin will automaticly move all items to the dropdown & change the toggle label to navDropdownBreakpointLabel. - Smart calculation of available space
It automatically looks for the main navigation's siblings and calculates remaining space. - Flexible
Because of the point above you can have multiple inline-block/flexbox items on the same level. - Non obstructive menu dropdown
The dropdown menu can be closed by clicking outside and pressing escape. - Callbacks
Callbacks are fired when an item is moved or moved back from the main navigation.
