Using multiple hubs blocks will improve the attendee event discovery experience. Trust us.
While you hold the key to unlock as many of the above card styles as you like, keep in mind that unlocking multiple hub card styles within a single hub element in any capacity will also "unlock" the Height Matching setting from being applied to all card styles.
If you plan to have multiple card designs and also want the card heights to always remain consistent, you'll need to add a separate hub for each card style (Featured, Past, Private, etc.). Then, only edit the Default card for each hub while keeping all other card styles locked.
Check out the video below to learn about the benefits of using multiple hub blocks to organize your events more effectively.
