Can I change the default location of the registration form on the product page?

The default location of the registration form can be changed. Go to the Settings -> Registration forms page of the app and edit the registration form, then select the Page placement tab. 

Adjusting the page placement can be tricky to people not familiar with how to identify the id or class of a <div> element on the product page. To have the team assist in adjusting the form placement on the page, please submit a support ticket with a link to product that is out of stock and describe where you would prefer the form to display.
