One approach is to use a combobox, that allows you to search. So on the Items of the Combobox put the Datasource: SCHOOLS.Title
If you want to filter a Gallery that is linked to the Dropdown or Combobox, you try:
Filter(Schools,Title=Combobox1.Selected.Title)
If you want whatever you select to Appear on a form, then:
On the Form Item put: Gallery1.Selected
Then on the Gallery1 put: Schools
So whatever you select in the Gallery appears on the form
A screenshot will help it it still does not work
