This is a js date entry widget built expressly for bootstrap. It's fairly thin, at 2.1K min/gz, but still somewhat extensible. It supports keyboard navigation, reverts to iOS native date entry, and a few other little features. It's pretty thoroughly tested in all the browsers that Bootstrap lists support for, although the visual design could probably be improved.
