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 >}} Open this select menu One Two Three {{< /example >}}

Sizing

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

{{< example >}} Open this select menu One Two Three Open this select menu One Two Three {{< /example >}}

The multiple attribute is also supported:

{{< example >}} Open this select menu One Two Three {{< /example >}}

As is the size attribute:

{{< example >}} Open this select menu One Two Three {{< /example >}}
