Option Options

No, you read that right. You can customize the options too. You can individually disable them, turn them into links and also change their color to any of the default colors:

Controlling Dropdowns Programmatically

You know how, this entire page, we’ve been assigning our DropdownHelper to a variable? There’s a reason for that. The DropdownHelper allows you to access some built-in functions for programmatically toggling, showing and hiding the dropdown. You can even register a callback for when one of the dropdowns options has been clicked!
