A simple example using the form-select class

  <option selected>Open this select menu</option>
  <option value="1">One</option>

  <option value="3">Three</option>
</select>

Sizing

Make large and small selects with form-select-lg and form-select-sm classes in addition of the common form-select.

<select
  class="mb-3 form-select form-select-lg"
  aria-label=".form-select-lg example"
>
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

<select class="form-select form-select-sm" aria-label=".form-select-sm example">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Create a multiple select by adding the boolean multiple attribute. Hold down the Ctrl (windows) or Command (Mac) button to select multiple options in the above example.

<select class="form-select" multiple aria-label="multiple select example">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Use the size attribute to determine the max amount of rows visible

<select class="form-select" size="3" aria-label="size 3 select example">
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Disabled

Disable a select using the disabled boolean attribute.

<select class="form-select" aria-label="Disabled select example" disabled>
  <option selected>Open this select menu</option>
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>
