This add-on allows you to filter the list in the Attendees & Tickets area based on whether attendees were checked-in or not. This comes particularly handy when trying to find out who showed up at the event and who missed it.
When installed and activated, this add-on will add another dropdown menu from where you can select Checked-in, Non-checked-in and Any (see the screenshot below).
Add-on is installed and activated like any other WordPress plugin and works with Tickera as a "standalone" as well as when used accompanied by WooCommerce via Bridge for WooCommerce.
