## Default

Custom `<select>` menus need only a custom class, `.form-select` to trigger the custom styles. Custom styles are limited to the `<select>`'s initial appearance and cannot modify the `<option>`s due to browser limitations.

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

## Sizing

You may also choose from small and large custom selects to match our similarly sized text inputs.

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

The `multiple` attribute is also supported:

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

As is the `size` attribute:

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