Add a popup name (slug-name) to your popup (required). This input is added to a class attribute ‘popmake-{slug-name}’ and assigned to the name of your popup. In the WP Admin, you’ll find the new class at ‘Popup Maker’ >> ‘All Popups’ >> ‘CSS Classes (column)’. The class can be used to set a Click Open trigger that links to a page element.
