Just wanted to comment that all the directives from http://angular-ui.github.com/bootstrap/ are native AngularJS directives. They don't require _any_ 3rd party JavaScript dependency (jQuery, bootstrap's JS etc.). Just take Angular, 5kB library (minified, gzipped) and you are ready to go!

On top of this all those directives are fully customizable as (almost) no DOM manipulation happens in directives, markup is extracted to separate templates: https://github.com/angular-ui/bootstrap/tree/master/template
