Hello,
There should be a setting in the listview widget named "Editable" or something like that. Please check it, enable it and let me know if that works or not. By default it's set to "NO" if it's inside another widget.
This is not a missing setting, it’s a Studio Pro limitation. A Gallery is already a data widget and has its own data context. When you place another data widget like a List View inside it, Studio Pro may not let you edit it properly in Design mode.
If you only want to show Name, don’t use a List View inside the Gallery. Set the Gallery datasource to the correct list (for example Farm_Worker) and place a simple Text widget inside the Gallery item, bound directly to Name (or Worker/Name).
If you really need a list inside each card, it’s better not to use a Gallery. Use a List View as the main widget and design it like cards with a Layout Grid, or redesign the page so the Gallery item does not contain another repeating data widget.
