Bootstrap optgroup selection

Question

I am using bootstrap select plugin with bootstrap 3.0.2, which fulfils most of my requirements.
The only additional functionality I want is to be able to select an optgroup by clicking it.

For example I would like to select Picnic (picture below) just like any other option,

Bootsrap select page

Answer 1

This has little to do with Bootstrap. optgroups in HTML are not designed to selected. My suggestion would be to drop them all together and just make them normal options with a class and style them differently. However keep in mind, that many browsers are limited to how you can style options, so make sure you test this in multiple browsers.
