Scenario:
Event registration, only one event ticket set up. The ticket bar appears, the number can be selected and the submit button "Register" is displayed. When the button is clicked, the selected number is submitted and the modal with the attendee form is loaded from the server.

Question:
How can I force the display of the form automatically or trigger it with a second button? This one ticket should be submitted and the number should be 1.

Thanks for any advice
