Form Builder overview

The Form Builder is where you decide what attendees tell you when they register. It's a visual, drag-and-drop editor — open Sign-up form from your event to start.

The editor

Drag fields onto the canvas and reorder them however you like. Each field has a label and can be required or optional. Because every label is stored per language, you build the form once and attendees see it in whichever of your event's languages applies.

The fields

You have different field types for specified input and validation. For exactly what each one does and the options it offers, see the Field types reference.

Paid and limited options

Dropdown, checkbox, and radio options can each carry a price and a capacity — that's how you sell ticket types and add-ons and cap how many of each are available. See Free & paid registration.

Admin-only fields

Some things you want to record about an attendee are not questions for the attendee: an internal note, a seating group, whether someone was comped. Open the field's settings and choose Make admin only. An amber banner confirms it, the field gets an Admin only badge on the canvas, and it disappears from the sign-up form entirely — attendees never see the question and it is never sent to their browser.

You fill these in yourself from the participants table, the same way you edit any other answer.

Two things follow from that. An admin-only field cannot be required — nobody would ever be able to answer it, and the attendee's form would stay unfinished forever — so turning admin-only on removes the required flag and hides the option. And because attendees can't choose an admin-only option, it shouldn't carry a price.

Editing after launch

You can keep refining the form after people have started signing up. Existing answers stay attached to their fields, so making compatible edits won't lose responses. But be careful when deleting fields, it removes them from the participants table!
