Description:
On a specific page built with SP Page Builder (Joomla 4/5 + Helix Ultimate), the off-canvas menu does not open in mobile landscape orientation.
The problem occurs only when a single Row contains many columns/items (in my case logos — over 20 image elements).
Reproducing:
Create a Row in SP Page Builder containing ~20–30 Columns (Image addons).
Open the page on a mobile device in landscape orientation.
Try to open the off-canvas menu.
Menu does not open, the page freezes.
No JavaScript errors visible in console.
Important:
Works in mobile portrait.
Works on desktop, even with the layout width reduced.
Works when I hide or remove a few columns (below ~19 elements).
Works if I split the Row into two smaller Rows.
Conclusion:
This is likely a layout/rendering conflict between SP Page Builder column structure and the Helix off-canvas script in mobile landscape mode.
Please investigate.
