If you’d chosen to list multiple amounts on a payment form or suggest multiple amounts on a payment form, you can also choose whether you’d like those amounts to be displayed as radio buttons or in a dropdown menu at checkout.
1) Create a new payment form (or find the one you’d like to edit.)
2) Once you’ve entered the multiple amounts, you’ll see a section titled
“How are amounts displayed?"
3) Choose whether you’d like the amounts to be displayed as radio buttons or in a drop down menu and save your choice.
4) Your selection will control how the amounts are displayed at checkout.
