Select

<wa-select>

Stable

Selects let users choose one or more values from a dropdown list of predefined options. Use them in forms when a fixed set of choices needs to fit in limited space.

  Option 1
  Option 2
  Option 3
  Option 4
  Option 5
  Option 6


                  
                

<wa-select>
  <wa-option value="">Option 1</wa-option>
  <wa-option value="option-2">Option 2</wa-option>
  <wa-option value="option-3">Option 3</wa-option>
  <wa-option value="option-4">Option 4</wa-option>
  <wa-option value="option-5">Option 5</wa-option>
  <wa-option value="option-6">Option 6</wa-option>
</wa-select>

This component works with standard <form> elements. Please refer to the section on form controls to learn more about form submission and client-side validation.

Multiple

Link to This Section

To allow multiple options to be selected, use the multiple attribute. It's a good practice to use with-clear when this option is enabled. You can select multiple options by adding the selected attribute to individual options.

  Option 1
  Option 2
  Option 3
  Option 4
  Option 5
  Option 6


                  
                

<wa-select label="Select a Few" multiple with-clear>
  <wa-option value="option-1" selected>Option 1</wa-option>
  <wa-option value="option-2" selected>Option 2</wa-option>
  <wa-option value="option-3" selected>Option 3</wa-option>
  <wa-option value="option-4">Option 4</wa-option>
  <wa-option value="option-5">Option 5</wa-option>
  <wa-option value="option-6">Option 6</wa-option>
</wa-select>

Selecting multiple options may result in wrapping, causing the control to expand vertically. You can use the max-options-visible attribute to control the maximum number of selected options to show at once.

Setting Initial Values

Link to This Section

Use the selected attribute on individual options to set the initial selection, similar to native HTML.

  Option 1
  Option 2
  Option 3
  Option 4

<wa-select>
  <wa-option value="option-1" selected>Option 1</wa-option>
  <wa-option value="option-2">Option 2</wa-option>
  <wa-option value="option-3">Option 3</wa-option>
  <wa-option value="option-4">Option 4</wa-option>
</wa-select>

For multiple selections, apply it to all selected options.

  Option 1
  Option 2
  Option 3
  Option 4

<wa-select multiple with-clear>
  <wa-option value="option-1" selected>Option 1</wa-option>
  <wa-option value="option-2" selected>Option 2</wa-option>
  <wa-option value="option-3">Option 3</wa-option>
  <wa-option value="option-4">Option 4</wa-option>
</wa-select>

Framework users can bind directly to the value property for reactive data binding and form state management.

Grouping Options

Custom Tags

Link to This Section

When multiple options can be selected, you can provide custom tags by passing a function to the getTag property. Your function can return a string of HTML, a Lit Template, or an HTMLElement. The getTag() function will be called for each option. The first argument is an <wa-option> element and the second argument is the tag's index (its position in the tag list).

Remember that custom tags are rendered in a shadow root. To style them, you can use the style attribute in your template or you can add your own parts and target them with the ::part() selector.

  
    Email
  
    Phone
  
    Chat

<wa-select placeholder="Select one" multiple with-clear class="custom-tag">
  <wa-option value="email" selected>
    <wa-icon slot="start" name="envelope" variant="solid"></wa-icon>
    Email
  </wa-option>
  <wa-option value="phone" selected>
    <wa-icon slot="start" name="phone" variant="solid"></wa-icon>
    Phone
  </wa-option>
  <wa-option value="chat">
    <wa-icon slot="start" name="comment" variant="solid"></wa-icon>
    Chat
  </wa-option>
</wa-select>

<script type="module">
  await customElements.whenDefined('wa-select');
  const select = document.querySelector('.custom-tag');
  await select.updateComplete;

  select.getTag = (option, index) => {
    // Use the same icon used in wa-option
    const name = option.querySelector('wa-icon[slot="start"]').name;

    // You can return a string, a Lit Template, or an HTMLElement here
    // Important: include data-value so the tag can be removed properly!
    return `
      <wa-tag with-remove data-value="${option.value}">
        <wa-icon name="${name}"></wa-icon>
        ${option.label}
      </wa-tag>
    `;
  };
</script>

Be sure you trust the content you are outputting! Passing unsanitized user input to getTag() can result in XSS vulnerabilities.

When using custom tags with with-remove, you must include the data-value attribute set to the option's value. This allows the select to identify which option to deselect when the tag's remove button is clicked.

Lazy Loading Options

Link to This Section

Lazy loading options works similarly to native <select> elements. The select component handles various scenarios intelligently:

Basic Lazy Loading Scenarios

Link to This Section

Empty select with value: If a <wa-select> is created without any options but given a value attribute, its value will be "" initially. When options are added later, if any option has a value matching the select's value attribute, the select's value will update to match.
Multiple select with partial options: If a <wa-select multiple> has an initial value with multiple options, but only some options are present in the DOM, it will respect only the available options. When additional selected options are loaded later (and the user hasn't changed the selection), those options will be automatically added to the selection.

Here's a comprehensive example showing different lazy loading scenarios:

    
      Bar
      Baz
    
    Add "foo" option
  
    Add "foo" option
  
      Bar
      Baz
    
    Add "foo" option (selected)
  
    Add "foo" option
  
    Reset
    Show FormData

<form id="lazy-options-example">
  <div>
    <wa-select name="select-1" value="foo" label="Single select (with existing options)">
      <wa-option value="bar">Bar</wa-option>
      <wa-option value="baz">Baz</wa-option>
    </wa-select>

    <wa-divider></wa-divider>

    <wa-button appearance="filled" type="button">Add "foo" option</wa-button>
  </div>

  <br />

  <div>
    <wa-select name="select-2" value="foo" label="Single select (with no existing options)"> </wa-select>

    <wa-divider></wa-divider>

    <wa-button appearance="filled" type="button">Add "foo" option</wa-button>
  </div>

  <br />

  <div>
    <wa-select name="select-3" multiple label="Multiple Select (with existing selected options)">
      <wa-option value="bar" selected>Bar</wa-option>
      <wa-option value="baz" selected>Baz</wa-option>
    </wa-select>

    <wa-divider></wa-divider>

    <wa-button appearance="filled" type="button">Add "foo" option (selected)</wa-button>
  </div>

  <br />

  <div>
    <wa-select name="select-4" value="foo" multiple label="Multiple Select (with no existing options)"> </wa-select>

    <wa-divider></wa-divider>

    <wa-button appearance="filled" type="button">Add "foo" option</wa-button>
  </div>

  <br /><br />

  <div style="display: flex; gap: 16px;">
    <wa-button appearance="filled" type="reset">Reset</wa-button>
    <wa-button appearance="filled" type="submit" variant="neutral">Show FormData</wa-button>
  </div>

  <br />

  <pre hidden><code id="lazy-options-example-form-data"></code></pre>

  <br />
</form>

<script type="module">
  function addFooOption(e) {
    const addFooButton = e.target.closest("wa-button[type='button']");
    if (!addFooButton) {
      return;
    }
    const select = addFooButton.parentElement.querySelector('wa-select');

    if (select.querySelector("wa-option[value='foo']")) {
      // Foo already exists. no-op.
      return;
    }

    const option = document.createElement('wa-option');
    option.setAttribute('value', 'foo');
    option.selected = true;
    option.innerText = 'Foo';

    // For the multiple select with existing selected options, make the new option selected
    if (select.getAttribute('name') === 'select-3') {
      option.selected = true;
    }

    select.append(option);
  }

  function handleLazySubmit(event) {
    event.preventDefault();

    const formData = new FormData(event.target);
    const codeElement = document.querySelector('#lazy-options-example-form-data');

    const obj = {};
    for (const key of formData.keys()) {
      const val = formData.getAll(key).length > 1 ? formData.getAll(key) : formData.get(key);
      obj[key] = val;
    }

    codeElement.textContent = JSON.stringify(obj, null, 2);

    const preElement = codeElement.parentElement;
    preElement.removeAttribute('hidden');
  }

  const container = document.querySelector('#lazy-options-example');
  container.addEventListener('click', addFooOption);
  container.addEventListener('submit', handleLazySubmit);
</script>

The key principle is that the select component prioritizes user interactions and explicit selections over programmatic changes, ensuring a predictable user experience even with dynamically loaded content.

`disabled` `disabled`	Disables the select control. Type `boolean` Default `false`
`form`	By default, form controls are associated with the nearest containing `<form>` element. This attribute allows you to place the form control outside of a form and associate it with the form that has this `id`. The form must be in the same document or shadow root for this to work. Type `HTMLFormElement \| null`
`getTag`	A function that customizes the tags to be rendered when multiple=true. The first argument is the option, the second is the current tag's index. The function should return either a Lit TemplateResult or a string containing trusted HTML of the symbol to render at the specified value. Type `(option: WaOption, index: number) => TemplateResult \| string \| HTMLElement`
`hint` `hint`	The select's hint. If you need to display HTML, use the `hint` slot instead. Type `string` Default `''`
`label` `label`	The select's label. If you need to display HTML, use the `label` slot instead. Type `string` Default `''`
`maxOptionsVisible` `max-options-visible`	The maximum number of selected options to show when `multiple` is true. After the maximum, "+n" will be shown to indicate the number of additional items that are selected. Set to 0 to remove the limit. Type `number` Default `3`
`multiple` `multiple`	Allows more than one option to be selected. Type `boolean` Default `false`
`name` `name`	The name of the select, submitted as a name/value pair with form data. Type `string \| null` Default `''`

`required` `required`	The select's required attribute. Type `boolean` Default `false`
`size` `size`	The select's size. Type `'xs' \| 's' \| 'm' \| 'l' \| 'xl' \| 'small' \| 'medium' \| 'large'` Default `'m'`
`validationTarget`	Where to anchor native constraint validation Type `undefined \| HTMLElement`
`validators`	Validators are static because they have `observedAttributes`, essentially attributes to "watch" for changes. Whenever these attributes change, we want to be notified and update the validator. Type `Validator[]` Default `[]`
`value` `value`	The select's value. This will be a string for single select or an array for multi-select.
`withClear` `with-clear`	Adds a clear button when the select is not empty. Type `boolean` Default `false`
