Reset Single fields on button click

Hi all

I have created a quick quote table to help with pricing jobs quickly. I tried using it on a mobile (android) and I hate the messy layout so I have created a run of single selections to get the same result but a nicer interface (It’s still very choppy and I’ll more than likely use an api and my own design later on but enough of that for now). Once I have chosen my choices I have a button at the end that adds a row to my quick quote table with all my choices.

So far this works fine but once the choices have been added to my table, I wish to reset the choice back to default.

How can I rest my choices using a button?
