Hello,
I am trying to use an existing SharePoint list with Managed Metadata columns. Those columns are what I am needing to filter my PowerApps Gallery along with one search box where I would need to incorporate the StartsWith() formula for "Title".

Due to being Metadata, I cannot effectively use formulas like “Distinct()” with “ClearCollect()” to create collections for filtering. Here is the formula that I have effectively used for one filter:
Dropdown box – Choices(MarketingAssetsLibrary.ProductTag).Label
Gallery - Filter(MarketingAssetsLibrary,Dropdown2.Selected.Label in ProductTag.Label).
The issue is, I can not find a good way to continue to use these formulas while also gaining the functionality to filter by multiple custom metadata dropdowns as well as a search box “Title” filter. I have tried “||”, And() and “&&” with no success. And as stated early I have tried creating table collections for each dropdown with no sucess.
I am also wanting to add an "ALL" for each dropdown (2). The only information I have seen on that (plus my needs above) utilizes the ClearCollect() formulas and standard SharePoint columns/data.
Any help you all could provide would be greatly appreciated!
Thank you!
