To enable pre-order buttons on your collection pages and homepage:
- Go to the Default Settings tab
- Scroll down to the Collections section
- Check the box Display pre-order buttons on homepage and collection pages
- Save your changes
- Ensure the pre-order buttons are appearing on your homepage and collection pages.
This feature is very theme dependent and does not work with all themes. If pre-order buttons aren't appearing, please contact support and we'll see if we can get it working with your theme.
