<h1>Filterable inside custom select</h1>
<p>
These examples show how you can filter the list inside a custom select menu.
</p>
<p>You can create an input field and prepend it to the popup and/or the dialog used by the custom select menu list and you can use it to filter items inside the list by instantiating a filterable widget on the select menu.</p>
