To set how the item displays in the list when being searched. From the "Main Title" dropdown, select the product information that should be used as the main title for the product in the list. We're going to use the "Name" field here so that the product name shows first when searching.
To show other fields when searching the list, use the "Add Display" multiple times to add more fields to the search display. In the example we have added two items - Sales Price and Code. In the text boxes on the left, we've specified the heading these fields should have in the search box.
