As you can see on the repo docs (http://silviomoreto.github.io/bootstrap-select/#disabled-option), when you set an option to disabled, and click to the anchor link, does not close the dropdown, working as expected, but when you click over the text of the same option, the event is propagged and the dropdown is closed.
