<h5>Getting Started</h5>
|
|
|
|
|
<p>
|
|
|
|
|
AutoComplete uses v-model for two-way binding, requires a list of suggestions and a complete method to query for the results. The complete method gets the query text as event.query property and should update the suggestions with the
|
|
|
|
|
search results. Example below connects to a remote datasource to fetch the results;
|
|
|
|
|

|

|
<pre v-code><code>
|
2022-09-09 20:41:18 +00:00
|
|
|
<AutoComplete v-model="selectedCountry" :suggestions="filteredCountriesBasic" @complete="searchCountry($event)" optionLabel="name" />

<h5>Dropdown</h5>
|
|
|
|
|
<p>
|
|
|
|
|
Enabling <i>dropdown</i> property displays a button next to the input field where click behavior of the button is defined using dropdownMode property that takes "blank" or "current" as possible values. "blank" is the default mode to
|
|
|
|
|
send a query with an empty string whereas "current" setting sends a query with the current value of the input.
|
|
|
|
|
</p>
|
|
|
|
|
<pre v-code><code>
|
2022-09-09 20:41:18 +00:00
|
|
|
<AutoComplete v-model="brand" :dropdown="true" :suggestions="filteredBrands" @complete="searchBrand($event)" placeholder="Hint: type 'v' or 'f'" />
|
|
|
|
|
|
|
|
|
|
</code></pre>
|
|
|
|
|
|
2022-09-14 14:26:41 +00:00
|
|
|
<h5>Multiple Mode</h5>
|
|
|
|
|
<p>Multiple mode is enabled using <i>multiple</i> property to select more than one value from the autocomplete. In this case, value reference should be an array.</p>
|
|
|
|
|
<pre v-code><code>
|
2022-09-09 20:41:18 +00:00
|
|
|
<AutoComplete :multiple="true" v-model="selectedCountries" :suggestions="filteredCountriesMultiple" @complete="searchCountryMultiple($event)" optionLabel="name" />
|
|
|
|
|
|
|
|
|
|
</code></pre>
|
|
|
|
|
|
2022-09-14 14:26:41 +00:00
|
|
|
<h5>Objects</h5>
|
|
|
|
|
<p>
|
|
|
|
|
AutoComplete can also work with objects using the <i>optionLabel</i> property that defines the label to display as a suggestion. The value passed to the model would still be the object instance of a suggestion. Here is an example with
|
|
|
|
|
a Country object that has name and code fields such as {name:"United States",code:"USA"}.
|
|
|
|
|
</p>
|
|
|
|
|
<pre v-code><code>
|
2022-09-09 20:41:18 +00:00
|
|
|
<AutoComplete optionLabel="label" v-model="selectedCountry" :suggestions="filteredCountriesBasic" @complete="searchCountryBasic($event)" />

|
|
|
<h5>Grouping</h5>
|
|
|
|
|
<p>Options groups are specified with the <i>optionGroupLabel</i> and <i>optionGroupChildren</i> properties.</p>

<h5>Force Selection</h5>
|
|
|
|
|
<p>
|
|
|
|
|
ForceSelection mode validates the manual input to check whether it also exists in the suggestions list, if not the input value is cleared to make sure the value passed to the model is always one of the suggestions. Simply enable
|
|
|
|
|
<i>forceSelection</i> to enforce that input is always from the suggestion list.

<h5>Templating</h5>
|
|
|
|
|
<p>
|
|
|
|
|
Item template allows displaying custom content inside the suggestions panel. The slotProps variable passed to the template provides an item property to represent an item in the suggestions collection. In addition <i>optiongroup</i>,
|
|
|
|
|
<i>chip</i>, <i>header</i> and <i>footer</i> slots are provided for further customization

Value to describe the component can either be provided via <i>label</i> tag combined with <i>inputId</i> prop or using <i>aria-labelledby</i>, <i>aria-label</i> props. The input element has <i>combobox</i> role in addition to
|
|
|
|
|
<i>aria-autocomplete</i>, <i>aria-haspopup</i> and <i>aria-expanded</i> attributes. The relation between the input and the popup is created with <i>aria-controls</i> and <i>aria-activedescendant</i> attribute is used to instruct
|
|
|
|
|
screen reader which option to read during keyboard navigation within the popup list.
|
|
|
|
|
</p>
|
|
|
|
|
<p>In multiple mode, chip list uses <i>listbox</i> role with <i>aria-orientation</i> set to horizontal whereas each chip has the <i>option</i> role with <i>aria-label</i> set to the label of the chip.</p>
|
|
|
|
|
<p>
|
|
|
|
|
The popup list has an id that refers to the <i>aria-controls</i> attribute of the input element and uses <i>listbox</i> as the role. Each list item has <i>option</i> role and an id to match the <i>aria-activedescendant</i> of the
|
|
|
|
|
input element.
