Hi Frank,
Thanks for checking out our plugins!
You can see all of the available default views here on our demo site, but the two that would be closest to a horizontal view would be photo or week. If you wanted to customize these or any of the other views, our themer’s guide has some instructions to help you do so.
You can indeed add different categories to events and use those to create separate calendar views. Our shortcodes and widgets that come with Events Calendar Pro can help with this, and The Events Calendar also creates archive pages for each category automatically.
We do offer full refunds within 30 days of purchase, so if you’d like to take Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
