In cases where you've used thegroup_labelparameter to combine fields into custom groups in a view's field picker, you can also use thegroup_item_labelparameter for each of the grouped fields to customize how the individual fields are shown in the field picker.
For example, you can add thegroup_labelto a set of fields like this:
These fields will now be combined into an expandableShipping Infosection in the field picker.
But since these fields are shown under the expandableShipping Infosection, they don't need to have "Shipping" in their individual labels as well. So you can add thegroup_item_labelparameter to each of the grouped fields:
Thegroup_item_labeldisplays only in the field picker. In the Data section of an Explore and in any visualizations, Looker displays the field's name or label as normal.
