I am building an application named School in powerapps with connecting to sharepoint list. I want my app to search for speacfic things like School Name and Area. I am not sure what to do. I tried to change the sort but my filter got screwed up and if i change my TextSearchBox1 niothing works but gets an error. I also would like to add dropdown controls and link to search, so users can search and select from dropdown to make navigation more particular.
