Add custom attributes to <select> options generated with Angular's ng-options

Question

With Bootstrap, you can very nicely define tooltips for <select> options (stackoverflow.com), while Angular can conveniently generate and bind options with the ngOptions attribute on a <select> element.

However, how can I add attributes to these generated option elements that can then be used by Bootstrap's tooltip plugin?

Answer 1

Looking at the source code of AngularJS in its current version (1.0.4 and 1.1.2) it is not possible as option elements are created inside JavaScript code without possibility to specify any additional attributes.
