Search within List Field

I have a form with several List Fields and I need to search only within the data that are present in the List Fields (in GravityView).

In GravityView under “Search Bar” the fields that are inside the List Field are not displayed.

It seems that the problem comes from structuring the database of List Fields in Gravity Forms that GravityView does not support them in Search Bar.

Would it be possible to fix this issue?

Thank you
