Hi, I'm (very) new to power apps and for my work I'm trying to build a small ecosystem within a sharepoint sandbox (it's in a sandbox for now, but will be moved to the company's proper sharepoint once it's acceptable) to allow a filter search by cascading dropdowns in a power apps application. I have a folder of documents, a list of all of the attributes of each file in said folder, and a list acting as a key to allow the cascading. Past this point I'm not sure where to go. I keep finding tutorials that use cascading dropdowns for the purpose of appending lists but not searching databases. Any help would be greatly appreciated and if i need to add info, just tell me. Thanks!
