The required ticket feature in Event Espresso 4 will let you set a specific ticket to required while allowing you to create other ticket options that are optional.
Here is an overview of the steps:
Login to your WordPress dashboard and go to Event Espresso --> Events. Then click on Add New or click on an existing event to edit an event that you have already created. Go ahead and enter basic event information such as a title and event description. Then edit the ticket option to enable the required option through the gear (advance options) icon. Then save changes to the event.
The best way to learn is to take a look at the video below and then try it out on your own. Don't worry about setting up something wrong and if you are not sure, then reach out via the Event Espresso support forums.
