Hi Max,
You cannot upload images directly here, you will need to upload to some image hosting site and then link them here. But, unfortunately, I doubt it would help very much if you just post a screenshot. That kind of error might be caused by many issues like invalid menu tree HTML structure (incorrectly nested tags, etc.), some JavaScript conflict, etc. So it’s really difficult to guess what exactly might be causing this without being able to test a live demo. So, if possible, please try to prepare some sort of test page that demonstrates the issue (I understand it would be impossible to test the real solution).
Thanks!
