Dropdown menu with text input filter at the top of the options?

Question

I have seen a component being used where you have a select menu, and when you drop down the options, there is a text input at the top. You can type in there to filter the select menu's options.

Unfortunately, I can't remember where I saw this, and I don't know what this type of component is called.

I am looking to do this with Bootstrap 3, if possible.

You're probably thinking of a plugin such as Select2 (or its predecessor, Chosen). Bootstrap had Typeahead in version 2, but it's apparently been dropped in favor of Bootstrap's standalone Typeahead plugin.
