Currently, PowerApps allows for nested galleries of 2 (one gallery with a single gallery inside of it).
I would like galleries to be expanded to allow for up to 3 levels of nesting.
(A gallery inside of a gallery inside of a gallery). A critical requirement of said nesting is that deeper levels can access the "ThisItem" parameter of parent galleries.
Example Application: Family Tree Display
Master Gallery.Items = Table of Generations (ThisItem gives you a generation which is a table of tables(families))
Middle Gallery.Items = ThisGeneration.Families (ThisItem gives you a table for a family in the generation)
Last Gallery.Items = ThisFamily.FamilyMember (ThisItem gives you an individual family member)
As per my title, I would like to see the nested capabilities expanded to AT LEAST 3 levels - however, hierarchical relationships are applicable in a wide range of applications/businesses. I could see this being a fantastic way to view/manipulate data in a hierarchical structure....but we need the nesting!
