The Aha! for Product Add filter button automatically updates available selections based on the columns you have chosen as part of your list or table.
This means that if you are on a Features > list, Roadmaps > List or the Roadmaps > Pivot views, the filter options dynamically change. This is because the potential list of filterable data in Aha! for Product is huge and we make it easy to find a filter to yield valuable results. Dynamically populating the filter ensures that only relevant data is available to be filtered at any given time.
