The idea is that I try to make my menu on the left toggable. Burger icon only on page load and menu content showing up on icon click (closing / disappearing on X icon click).
I have a vertical menu content and I have put it in on the left smaller (1/4) column. I was thinking about custom JS / CSS code but I thought about using some available features. I gave a try to accordion element first but it was not so much usable without series of modifications.
Toggle Row feature in Content Band Settings on the other hand sounds like a very good idea to start with, but …
with “Make row toggable” enabled and “Default state” set to closed my menu content is visible as usual and no other setting seems to force it to hide on page load.

To be sure that it is not my menu content causing the problem I tried to put simple text inside Content Band element but without any luck - situation stays the same.
Clicking icon or toggle title (no matter what is set) doesn’t change content visibility.
Is it Toggle Row feature bug or am I missing something here? Do you have any ideas how to fix the issue? Or maybe alternative idea how to make it work temporary without Content Band element?
