Bootstrap 3 Typeahead

For simple autocomplete use cases there seems to be nothing wrong with the dropped typeahead plugin. Here you will find the typeahead autocomplete plugin for Twitter's Bootstrap 2 ready to use with Twitter's Bootstrap 3. The original code is written by @mdo and @fat.

Users who migrate their website or app from Twitter's Bootstrap 2 to Bootstrap 3 can also use this plugin to keep their current autocomplete functions. See for a complete list of migrations steps: Migrate your templates from Twitter Bootstrap 2.x to Twitter Bootstrap 3

With Twitter Bootstrap 3 the typeahead plugin had been dropped. @mdo says: "in favor of folks using Twitter's typeahead. Twitter's typeahead has more features than the old bootstrap-typeahead.js and less bugs." Twitter's typeahead don't work direct with Bootstrap 3. The DOM structure of the dropdown menu used by typeahead.js differs from the DOM structure of the Bootstrap dropdown menu. You'll need to load some additional CSS in order to get the typeahead.js dropdown menu to fit the default Bootstrap theme.

Typeahead.js doesn't seem ready for the new Twitter Bootstrap 3 at the moment. Code is not up to date and fixes are need. See also: Typeahead problems with Bootstrap 3.0 RC1.

Download

• Download the latest boostrap3-typeahead.js or bootstrap3-typeahead.min.js.

• Include it in your source after jQuery and Bootstrap Javascript.

Full integration with Bootstrap 3 Typeahead

Download the latest version of Boostrap from Bootstrap. Copy bootstrap3-typeahead.js to the js/ folder. Edit gruntfile.js and add bootstrap3-typeahead.js to the plugins' list. Build your own version with typeahead with grunt dist.

CSS

There is no additional css required to use the plugin. Bootstrap's css contains all required styles in the .dropdownmenu class. The original CSS add a z-index of 1051 to the dropdownmenu via the typeahead class. You could add this if you need it. .typeahead { z-index: 1051;} (less or css).

Usage

You'll want to set autocomplete="off" to prevent default browser menus from appearing over the Bootstrap typeahead dropdown.
