So after a cascading dropdown, a specific button will show up, connected to a PDF file or an image.
So if the client choose he wants a women’s shirt size M, a button with “Size M Template” will show up, and if a client choose a man’s shirt size XL, a button with “Size XL Template” will show up.
Those buttons must be connected to different files, so exactly what the client choose will appear on the exact button.
