|Note: Make sure you are logged-in and in the correct event|
To avoid long registration forms with many "Colleagues" sections for participants who will not invite anyone:
Add an extra question in your form asking the specific number of additional participants (e.g. "How many colleagues will join you in our event?")
a. Create "Custom Registration Field"
Apply dependency on each colleague's section. The correct colleague sections (e.g. Colleague 1 and Colleague 2) will show up when the participant responds to the question "How many colleagues will join you in our event?" (e.g. "Two").
