How can I edit anything on the grid?
If you want to edit something right on the grid, you should make the corresponding column editable. To achieve that you need to navigate to “Grid Attribute Columns” and tick those fields that should be editable, this can be done on all the tabs: Standard Columns, Attribute Columns and Extra Columns. After that, save the changes of the existing template or add them to a new one.
