This is off-topic, but I find bootstrap dropdown menu code to be lacking in several areas: 1) I haven't been able to figure out how to have the same dropdown pop up on multiple triggers without cloning the menu for each trigger. 2) It doesn't automatically drop up or down based on the location of the trigger in the page. For example if the trigger is near the bottom of the page the menu should pop up, otherwise down. 3) It seems like the popup needs to be in the same container div as the trigger so depending on overflow you sometimes end up having to scroll to see the menu. Am I just not using it right? Are there other jQuery / javascript popup menus that have these features or add them to bootstrap?
