If you have a series of repeating events such as a class or lecture you can allow your event attendees to sign up for these multi-day events at once using "Self-Book." In the custom Self-Book templates for the "Book an Appointment" and "Group Sign-Up" you have an option to turn your Self-Book event into a multiple-day event signup.

By default when you have a multi-day event, the signup link for your event only shows up on the first day of the event. When someone signs up for an event in this series, their sign-up will appear in every Event in this series. See the image below:

If you need the signup link to appear on every day of your multi-day event you can turn this option on in the Self-Book template for your "Book an Appointment" and "Group Sign-Up" events. 

First, you'll need to open up a new template. Follow the steps in the image below:

When you have a new template (or your edited template) open you can then check on the box next to "Show Every Link" under the "Multi-day" option. See the image below:

Once this feature has been turned on, your sign-up link will show up every day of the multi-day event. When someone signs up for an event in this series, their sign-up will still appear in every Event in this series. See the image below:
