## Usage
|
|
|
|
The `SelectMenu` component renders by default a [Select](/forms/select) component and is based on the `ui.select` preset. You can use most of the `Select` props to configure the display if you don't want to override the default slot such as [color](/forms/select#style), [variant](/forms/select#style), [size](/forms/select#size), [placeholder](/forms/select#placeholder), [icon](/forms/select#icon), [disabled](/forms/select#disabled), etc.
|
|
|
|
Like the `Select` component, you can use the `options` prop to pass an array of strings or objects.
|
|
|
|
:component-example{component="select-menu-example-basic" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### Multiple
|
|
|
|
You can use the `multiple` prop to select multiple values.
|
|
|
|
:component-example{component="select-menu-example-multiple" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### Objects
|
|
|
|
You can pass an array of objects to `options` and either compare on the whole object or use the `by` prop to compare on a specific key. You can configure which field will be used to display the label through the `option-attribute` prop that defaults to `label`.
|
|
|
|
:component-example{component="select-menu-example-objects" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
If you only want to select a single object property rather than the whole object as value, you can set the `value-attribute` property. This prop defaults to `null`.
|
|
|
|
:component-example{component="select-menu-example-objects-value-attribute" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### Icon
|
|
|
|
Use the `selected-icon` prop to set a different icon or change it globally in `ui.selectMenu.default.selectedIcon`. Defaults to `i-heroicons-check-20-solid`.
|
|
|
|
::component-card
|
|
---
|
|
baseProps:
|
|
class: 'w-full lg:w-40'
|
|
placeholder: 'Select a person'
|
|
options: ['Wade Cooper', 'Arlene Mccoy', 'Devon Webb', 'Tom Cook', 'Tanya Fox', 'Hellen Schmidt', 'Caroline Schultz', 'Mason Heaney', 'Claudie Smitham', 'Emil Schaefer']
|
|
props:
|
|
selectedIcon: 'i-heroicons-hand-thumb-up-solid'
|
|
excludedProps:
|
|
- selectedIcon

::callout{icon="i-heroicons-light-bulb"}
|

Learn how to customize icons from the [Select](/forms/select#icon) component.

|
### Search
|
|
|
|
Use the `searchable` prop to enable search.
|
|
|
|
Use the `searchable-placeholder` prop to set a different placeholder.
|
|
|
|
This will use Headless UI [Combobox](https://headlessui.com/vue/combobox) component instead of [Listbox](https://headlessui.com/vue/listbox).

props:
|
|
searchable: true
|
|
searchablePlaceholder: 'Search a person...'

|
|
### Async search
|
|
|
|
Pass a function to the `searchable` prop to customize the search behavior and filter options according to your needs. The function will receive the query as its first argument and should return an array.
|
|
|
|
Use the `debounce` prop to adjust the delay of the function.
|
|
|
|
:component-example{component="select-menu-example-async-search" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### Create option
|
|
|
|
Use the `creatable` prop to enable the creation of new options when the search doesn't return any results (only works with `searchable`).
|
|
|
|
Try to search for something that doesn't exist in the example below.
|
|
|
|
:component-example{component="select-menu-example-creatable" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
## Popper
|
|
|
|
Use the `popper` prop to customize the popper instance.
|
|
|
|
### Arrow
|
|
|
|
:component-example{component="select-menu-example-arrow"}
|
|
|
|
### Placement
|
|
|
|
:component-example{component="select-menu-example-placement"}
|
|
|
|
### Offset
|
|
|
|
:component-example{component="select-menu-example-offset"}
|
|
|
|
## Slots
|
|
|
|
### `label`
|
|
|
|
You can override the `#label` slot and handle the display yourself.
|
|
|
|
:component-example{component="select-menu-example-multiple-slot" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### `default`
|
|
|
|
You can also override the `#default` slot entirely.
|
|
|
|
:component-example{component="select-menu-example-button" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### `option`
|
|
|
|
Use the `#option` slot to customize the option content. You will have access to the `option`, `active` and `selected` properties in the slot scope.
|
|
|
|
:component-example{component="select-menu-example-option-slot" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### `option-empty`
|
|
|
|
Use the `#option-empty` slot to customize the content displayed when the `searchable` prop is `true` and there is no options. You will have access to the `query` property in the slot scope.
|
|
|
|
:component-example{component="select-menu-example-option-empty-slot" :componentProps='{"class": "w-full lg:w-40"}'}
|
|
|
|
### `option-create`
|
|
|
|
Use the `#option-create` slot to customize the content displayed when the `creatable` prop is `true` and there is no options. You will have access to the `query` property in the slot scope.
|
|
|
|
::callout{icon="i-heroicons-light-bulb"}
|
|
An example is available in the [Create option](#create-option) section.
