Tables inside Layout Grid invisible in Design View
Posted: Fri Jun 19, 2026 9:36 am
Hi Pablo,
I have encountered a specific workspace rendering bug in WYSIWYG Web Builder 21 that was not present in any of the previous versions.
Context:
The project was originally created in WWB 18, then successfully maintained and edited in WWB 20 without any issues. The problem appeared only after opening and working on the project in WWB 21.
Problem description:
When a standard Table object (imported from the older versions) is placed inside a Layout Grid, its content becomes completely invisible in the workspace (Design View). Curiously, after previewing or publishing the page, the table renders perfectly fine in the browser. The issue is strictly isolated to the WWB 21 editor workspace.
Steps to reproduce:
Open a project upgraded from v18/v20 in WWB 21.
Observe a Table object located inside a Layout Grid column.
The table is completely invisible in the Design View (though it still appears in the Object Manager).
Temporary workaround:
If I drag the Table outside the Layout Grid, it becomes visible again in the editor. Also, if I wrap the Table inside a standard Container/Flexbox Container and then place that container inside the Layout Grid, it remains visible.
It seems like the new v21 workspace rendering engine fails to properly calculate the height/overflow of legacy tables when they are direct children of a Layout Grid.
Could you please look into this backward compatibility rendering bug?
