Description

Issue: When a layout component is included in the edit grid and input components are added inside the layout component, the table is generated without considering the layout component. As a result, all nested components are skipped, leading to an empty grid.

Solution: Add a check to determine if the component is a layout component and iterate through all possible nested components using the everyComponent method.
