Select: Overview

A web component that works as a wrapper around the native select.

You cannot use interactive elements inside the options. Avoid very long names to facilitate the understandability and perceivability for screen reader users. Sets of options where each option name starts with the same word or phrase can also significantly degrade usability for keyboard and screen reader users.

export const main = () => html`
  <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">Hotpink</option>
      <option value="teal">Teal</option>

For this form element it is important to put the slot="input" with the native select yourself, because you are responsible for filling it with <option>s. For most other form elements we do this for you, because there's no need to put html inside the native form inputs.


  • Catches and forwards the select events
  • Can be set to required or disabled
