Hi Dobie,
There is not a built-in way to display categories as icons. If you have another plugin on your site that does this, you would need to check to see if it works with custom post types. (Events are the “tribe_events” post type.)
Alternatively, you could do a customization – our themer’s guide is the place to start if you would like to give this a shot! If this is a feature that you would like to see added in the future, please do let us know over in our Feature Ideas Forum! This is what we use to gauge user interest in new features and help guide future development efforts.
While we are limited in the amount of support that we can provide for third-party plugin integrations, if you can send me a link to the plugin that you are using to do this with other categories, I’ll be happy to take a look and see if there is anything that I can recommend!
One other thing I would note is that event categories are a taxonomy that exists only on events, but the tags that you can add to events are the same tags as are on posts. So, if the plugin works for tags, then you might want to try using those instead.
Please let me know if you have any questions!
Thanks,
Jennifer
