I used the bootstrap dropdown button in my backend module and recognize a weird behavior. The button always disappear after clicking on it. After four hours trying to find a solution i found that the for that behavior relies on a conflict between bootstrap and PrototypeJS.


The site describe the problem very well and offers two solutions. Please implement one of them. It seems to be that not only the dropdown function is affected.

can you please test again with current master? We use dropdown buttons (SplitButton) within the new DocHeaders. There is no problem.
If the problem still occurs, can you provide a demo extension?
