Pre-select

You can preselect an option by setting the property modelValue.

<lion-select name="favoriteColor" label="Favorite color" .modelValue=${'hotpink'}>
  <select slot="input">
    <option selected hidden value>Please select</option>
    <option value="red">Red</option>
    <option value="hotpink">Hotpink</option>
    <option value="teal">Teal</option>
  </select>
</lion-select>

Disabled

You can disable an option by adding the disabled attribute to an option.

<lion-select name="favoriteColor" label="Favorite color">
  <select slot="input">
    <option selected hidden value>Please select</option>
    <option value="red">Red</option>
    <option value="hotpink" disabled>Hotpink</option>
    <option value="teal">Teal</option>
  </select>
</lion-select>

Or by setting the disabled attribute on the entire lion-select field.

<lion-select name="favoriteColor" label="Favorite color" disabled>
  <select slot="input">
    <option selected hidden value>Please select</option>
    <option value="red">Red</option>
    <option value="hotpink">Hotpink</option>
    <option value="teal">Teal</option>
  </select>
</lion-select>

Validation

A validator can be used to make it e.g. required. If you want to know how to do that, please take a look at our validation examples.
