Original PR description

This commit resolves an issue with the quiz question section:
- Excessive white space when creating a new record.
- Overly wide layout in existing records, requiring horizontal scrolling.

**Technical**:
In grid groups, the layout enforces two columns:
- A smaller left column (max 150px).
- A right column that occupies the remaining space. 

When adding an element with nolabel="1", it occupies only one part of the grid.
To span the full width, colspan="2" must be explicitly set.
