<h5>Import via Module</h5>
<pre v-code.script><code>
import MultiSelect from 'primevue/multiselect';
</code></pre>
<h5>Import via CDN</h5>
<pre v-code><code>
&lt;script src="https://unpkg.com/primevue@^3/core/core.min.js"&gt;&lt;/script&gt;
&lt;script src="https://unpkg.com/primevue@^3/multiselect/multiselect.min.js"&gt;&lt;/script&gt;
</code></pre>
<h5>Getting Started</h5>
<p>MultiSelect 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>
&lt;MultiSelect v-model="selectedCars" :options="cars" optionLabel="brand" placeholder="Select Brands" /&gt;
</code></pre>
<pre v-code.script><code>
data() {
return {
selectedCars: null,
cars: [
{brand: 'Audi', value: 'Audi'},
{brand: 'BMW', value: 'BMW'},
{brand: 'Fiat', value: 'Fiat'},
{brand: 'Honda', value: 'Honda'},
{brand: 'Jaguar', value: 'Jaguar'},
{brand: 'Mercedes', value: 'Mercedes'},
{brand: 'Renault', value: 'Renault'},
{brand: 'Volkswagen', value: 'Volkswagen'},
{brand: 'Volvo', value: 'Volvo'}
]
}
}
</code></pre>
<h5>Chips Display</h5>
<p>A comma separated list is used by default to display selected items whereas alternative chip mode is provided using the <i>display</i> property to visualize the items as tokens.</p>
<pre v-code><code>
&lt;MultiSelect v-model="selectedCars" :options="cars" optionLabel="brand" placeholder="Select Brands" display="chip"/&gt;
</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 {
selectedGroupedCities: 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'},
{label: 'San Francisco', value: 'San Francisco'}
]
},
{
label: 'Japan', code: 'JP',
items: [
{label: 'Kyoto', value: 'Kyoto'},
{label: 'Osaka', value: 'Osaka'},
{label: 'Tokyo', value: 'Tokyo'},
{label: 'Yokohama', value: 'Yokohama'}
]
}]
}
}
}
</code></pre>
<pre v-code><code><template v-pre>
&lt;MultiSelect v-model="selectedGroupedCities" :options="groupedCities"
optionLabel="label" optionGroupLabel="label" optionGroupChildren="items"&gt;
&lt;/MultiSelect&gt;
</template>
</code></pre>
<h5>Filtering</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>
&lt;MultiSelect v-model="selectedCars" :options="cars" :filter="true" optionLabel="brand" placeholder="Select Brands"/&gt;
</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>value</i>, <i>optiongroup</i>, <i>chip</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><template v-pre>
&lt;MultiSelect v-model="selectedCars2" :options="cars" optionLabel="brand" placeholder="Select a Car"&gt;
&lt;template #value="slotProps"&gt;
&lt;div class="p-multiselect-car-token" v-for="option of slotProps.value" :key="option.brand"&gt;
&lt;img :alt="option.brand" :src="'demo/images/car/' + option.brand + '.png'" /&gt;
&lt;span&gt;{{option.brand}}&lt;/span&gt;
&lt;/div&gt;
&lt;template v-if="!slotProps.value || slotProps.value.length === 0"&gt;
Select Brands
&lt;/template&gt;
&lt;/template&gt;
&lt;template #option="slotProps"&gt;
&lt;div class="p-multiselect-car-option"&gt;
&lt;img :alt="slotProps.option.brand" :src="'demo/images/car/' + slotProps.option.brand + '.png'" /&gt;
&lt;span&gt;{{slotProps.option.brand}}&lt;/span&gt;
&lt;/div&gt;
&lt;/template&gt;
&lt;/MultiSelect&gt;
</template>
</code></pre>
