Can I open the wheel from my own button or menu link?

Yes. Link anything to the address #trlw-open: a menu item (a Custom Link in Appearance → Menus), a button or a banner image. Pressing it opens the popup on the page the shopper is on. Put #trlw-open on the end of a page address in a newsletter or a social post, such as https://yourshop.com/sale/#trlw-open, and that page opens with the wheel open. Anything with the class trlw-open opens it too, and the shortcode [trasl_lucky_wheel_button] draws a button in your theme's style. All three are on the Display screen under Open it from your own links, ready to copy.

A link opens the wheel even for a shopper who closed it or pressed No thanks, and on phones where it does not open by itself. It works on the pages the wheel shows on; the button brings the wheel to any page you put it on. Outside the Schedule, or with the wheel switched off, a link does nothing. The spin limits still apply: a second spin with the same email gets the usual message, not another prize.
