I thank the admins who have totally deleted my message without any warning and I propose it again here.
When you say you have a sub list based on a category does that mean you have a Gallery or DataTable in PowerApps that is being filtered by the category? If so, what is the formula for the Items property of the Gallery or DataTable? Also when a refresh is executed is Refresh('[dbo].[ Table]')
It's a Gallery and the formula that generate it is:
GroupBy(SortByColumns(Search('[dbo].[Table]'; TextSearchBox2.Text; "Category"); "Category"; If(SortDescending1; SortOrder.Descending; SortOrder.Ascending));"Category";"Category")
I understand the issue now. The selected item in the gallery changes to the first item when the gallery updates because of of an item being added or a manual refresh. This is being caused by the GroupBy function because it has to rebuild the table. I am sorry but I don't have a solution for you other than removing the GroupBy.
Reopen responsibly, monitor intelligently, and protect continuously with solutions for a safer work environment.
