Showcar-ui is the pattern library that is used to build the frontend of AutoScout24. It provides CSS classes, custom elements and components.

<h2>Custom dropdown default<span class="status refactor">Needs refactoring</span><span class="status js">JS</span></h2>

If the options list in the select is too big, you might need an user-friendly scrollbar: just add `scrollable` attribute on `<custom-dropdown>` tag (see examples below).<br>

If you want to use it in a react (or preact) project you might need to use `shouldComponentUpdate` method to avoid unexpected state changes.<br />Just add it as a method of you class:

`shouldComponentUpdate() {
    return false;
}`
