In this tab, you can add (add type of participation button) and edit any number of types of participation. They will be available for selection in the registration form, in the select field defined as Participation Type that you can configure in the Registration Form Sections tab. For every type of participation, provide its name, Invitation code (optional), and Registration limit - determining how many attendees can register with this type of participation. Use the icons on the right to manage defined types of participation.

In the upper part of this interface, you will find tools that let you easily browse and search types of participation, which may prove invaluable when dealing with bigger numbers of types of participation. 

CAUTION! Registration limits for types of participation are initiated with the value of 0. This means that until you input a number into the Registration limit field and save changes, it will not be possible to register as this participation type. In order to lift the limit, simply input a big number like 999999999. Also note that registration limits for different language versions are separate.
