I can see the problem on your website. I would like to replicate it locally, but I can’t. Would it be possible to copy the structure of your menu, and paste it here, so I can check it the same as you have it?
Or if you can, can you send temporary login credentials to your website and a link to this thread to help@bricksbuilder.io using the email address you used during the purchase, so we can take a look?
I was able to reproduce the issue locally. The problem is that you have a condition on this element (that should not be removed), because the code is always expecting it.
I’ll make an internal improvement task on this, but for now, I suggest that you remove the condition from the “Content (CSS)” element and put it on a parent (dropdown) itself.
Then, you add another element (text link for example), and you show it only when you are not showing a dropdown.
Thant should solve the issue for now. We will update this thread when we improve this.
