Hi Colm,
Thanks for reaching out to us on this!
First of let me say that the UNC calendar is highly customized by the custom theme they are using. There’s no option in our plugin to make the view buttons look like this.
The way to craft this cutomization is to create a template override of the events bar view file (wp-content/plugins/the-events-calendar/src/views/modules/bar.php), and change how the views menu is generated. Be sure to check our themer’s guide for more details on how to do this.
Best,
Nico
