Getting the currently focused index/item in a Select

[therealphatmike]

Hey all,

I can't seem to find a way to get the currently focused index or item from a select list. I have a select list on the left with just a simple name field, and as the user arrows through the form, I would like to render expanded information on the right. Is there a way to achieve this without having the user press enter? I would prefer the experience to not require the user to hit enter twice to fully select an option.

Here's a screen shot as an example, as you can see my MySQL entry is selected but the PG db info still gets rendered.

So far the only way I could find to do this would be to force the user to make the selection so it updates form state and I could retrieve it with m.Form.GetInt("database") and then update the expanded view. But then to select and connect to the DB, the user has to hit enter again and I have to force the model into some intermediary state in the interim. I did a search and did not find what I was looking for in docs, examples, or discussions.

Thanks in advance!

I solved my own discussion here. Apologies for opening and closing a discussion so quickly. I didn't see the Accessor stuff until after I posted this. I was able to use the accessor to get the functionality I desired. Perhaps I will add an example to the examples directory for this type of use case.

For anyone curious I just added an accessor to my model, passed the accessor into the form, and then used m.accessor.Get() to retrieve the currently selected value.

focused := new(databases.Database)
accessor := huh.NewPointerAccessor(focused)

return SelectDatabase{
	ready:         true,
	width:         width,
	height:        height,
	selectableDbs: availableDbs,
	accessor:      accessor,
	form: huh.NewForm(
		huh.NewGroup(
			huh.NewSelect[databases.Database]().
				Title("Which database would you like to connect to?").
				Key("database").
				Accessor(accessor).
				Options(dbOptions...),
		),
	),
}

func (m SelectDatabase) View() string {
    	// do any prep
    	
        highlightedDb := m.accessor.Get()

        // render your content with highlightedDb
}
