<h5>Import via Module</h5>
|
|
<pre v-code.script><code>
|
|
import Listbox from 'primevue/listbox';
|
|
|
|
</code></pre>
|
|
|
|
<h5>Import via CDN</h5>
|
|
<pre v-code><code>
|
|
<script src="https://unpkg.com/primevue@^3/core/core.min.js"></script>
|

<script src="https://unpkg.com/primevue@^3/listbox/listbox.min.js"></script>
|
|
|
|
</code></pre>
|
|
|
|
<h5>Getting Started</h5>
|
|
<p>Listbox requires a value to bind and a collection of arbitrary objects along with the <i>optionLabel</i> property to specify the label property of the option.</p>
|
|
<pre v-code><code>
|
|
<Listbox v-model="selectedCity" :options="cities" optionLabel="name" />
|
|
|
|
</code></pre>
|
|
|
|
<pre v-code.script><code>
|
|
data() {
|
|
return {
|
|
selectedCity: null,
|
|
cities: [
|
|
{name: 'New York', code: 'NY'},
|
|
{name: 'Rome', code: 'RM'},
|
|
{name: 'London', code: 'LDN'},
|
|
{name: 'Istanbul', code: 'IST'},
|
|
{name: 'Paris', code: 'PRS'}
|
|
]
|
|
}
|
|
}
|
|
|
|
</code></pre>
|
|
|
|
<h5>Selection</h5>
|
|
<p>
|
|
Listbox allows selection of either single or multiple items. In single case, model should be a single object reference whereas in multiple case should be an array. Multiple items can either be selected using metaKey or toggled
|
|
individually depending on the value of <i>metaKeySelection</i> property value which is true by default. On touch enabled devices metaKeySelection is turned off automatically.
|
|
</p>
|
|
<pre v-code><code>
|
|
<Listbox v-model="selectedCity" :options="cities" optionLabel="name" :multiple="true"/>
|
|
|
|
</code></pre>
|
|
|
|
<h5>Grouping</h5>
|
|
<p>Options groups are specified with the <i>optionGroupLabel</i> and <i>optionGroupChildren</i> properties.</p>
|
|
<pre v-code.script><code>
|
|
export default {
|
|
data() {
|
|
return {
|
|
selectedGroupedCity: null,
|
|
groupedCities: [{
|
|
label: 'Germany', code: 'DE',
|
|
items: [
|
|
{label: 'Berlin', value: 'Berlin'},
|
|
{label: 'Frankfurt', value: 'Frankfurt'},
|
|
{label: 'Hamburg', value: 'Hamburg'},
|
|
{label: 'Munich', value: 'Munich'}
|
|
]
|
|
},
|
|
{
|
|
label: 'USA', code: 'US',
|
|
items: [
|
|
{label: 'Chicago', value: 'Chicago'},
|
|
{label: 'Los Angeles', value: 'Los Angeles'},
|
|
{label: 'New York', value: 'New York'},
|

|
|
items: [
|
|
{label: 'Kyoto', value: 'Kyoto'},
|

{label: 'Osaka', value: 'Osaka'},
|

{label: 'Tokyo', value: 'Tokyo'},
|
|
{label: 'Yokohama', value: 'Yokohama'}

|
|
<pre v-code><code>
|
|
<Listbox v-model="selectedGroupedCity" :options="groupedCities"
|
|
optionLabel="label" optionGroupLabel="label" optionGroupChildren="items">
|
|
</Listbox>
|
|
|
|
</code></pre>
|
|
|
|
<h5>Filter</h5>
|
|
<p>
|
|
Filtering allows searching items in the list using an input field at the header. In order to use filtering, enable <i>filter</i> property. By default, optionLabel is used when searching and <i>filterFields</i> can be used to customize the
|
|
fields being utilized. Furthermore, <i>filterMatchMode</i> is available to define the search algorithm. Valid values are "contains" (default), "startsWith" and "endsWith".
|
|
</p>
|
|
<pre v-code><code>
|
|
<Listbox v-model="selectedCity" :options="cities" optionLabel="name" :filter="true"/>
|
|
|
|
</code></pre>
|
|
|
|
<h5>Templating</h5>
|
|
<p>
|
|
Label of an option is used as the display text of an item by default, for custom content support define an <i>option</i> template that gets the option instance as a parameter. In addition <i>optiongroup</i>, <i>header</i>, <i>footer</i>,
|
|
<i>emptyfilter</i> and <i>empty</i> slots are provided for further customization.
|
|
</p>
|
|
<pre v-code><code>
|
|
<Listbox v-model="selectedCars" :options="cars" :multiple="true" :filter="true" optionLabel="brand" listStyle="max-height:250px" style="width:15em">
|
|
<template #option="slotProps">
|
|
<div>
|
|
<img :alt="slotProps.option.brand" :src="'demo/images/car/' + slotProps.option.brand + '.png'" />
|
|
<span>{{slotProps.option.brand}}</span>
|
|
</div>

</template>
|
|
</Listbox>
|
|

<h5>Accessibility</h5>
|
|
<h6>Screen Reader</h6>
|
|
<p>
|
|
Value to describe the component can be provided <i>aria-labelledby</i> or <i>aria-label</i> props. The list element has a <i>listbox</i> role with the <i>aria-multiselectable</i> attribute that sets to true when multiple selection is
|
|
enabled. Each list item has an <i>option</i> role with <i>aria-selected</i> and <i>aria-disabled</i> as their attributes.
|
|
</p>
|
|
<p>If filtering is enabled, <i>filterInputProps</i> can be defined to give <i>aria-*</i> props to the input element. Alternatively <i>filterPlaceholder</i> is usually utilized by the screen readers as well.</p>
|
|
<pre v-code><code>
