From matrix chat - Wed, Feb 25, 2026 and after

Sorry if that doesn't sound hard core dev, but I could salvage 2 Tiki29 I updated in the last 2 days, by discarding last changes (reverting) on these 4 files:

src/js/jquery-tiki/tiki-menu.js - Menu JavaScript functionality
templates/bootstrap_smartmenu.tpl - Main menu template
templates/bootstrap_smartmenu_children.tpl - Submenu template
themes/base_files/scss/_tiki-menus.scss - Menu styling (SCSS)
(I had to re-applied my own other fixes and custom)
If it help anyone...

I've been trying to reproduce the problem in a Tiki 27 instance where Smartmenus work but so far haven't been able to. One problem I see in the image and video demonstrating the problem is a z-index issue with the menu dropdown displaying underneath the page header, so this blocks access to the top items of the dropdown. In my test with a fairly current branch 27, that is fixed so the top of the dropdown is accessible.

So in viewports taller than the dropdown, the whole dropdown displays. In viewports shorter than the dropdown, the cutoff end of the dropdown gets an up arrow (at the bottom of the viewport) or a down arrow (at the top of the viewport) to scroll the dropdown items.

So I don't see the original problem that needed solving. If I'm missing something, hopefully somebody can let me know.
