Form fields reference
Look up the participation form field types, build rules, and where participant answers appear.
Look up the field types you can add to a participation form, the rules to keep in mind while you build it, and where participant answers show up afterwards.
Use stable field labels
CSV exports use your field labels as column headers. Choose labels that will still make sense when you review answers later.
Supported field types
| Field type | What the participant sees | Notes for building the form |
|---|---|---|
| Text | A one-line free-text box | Good for short answers such as city, code, or a short comment |
| An email box | OmniLab checks the email format | |
| Number | A number box | Accepts numbers only |
| Telephone | A phone number box | Use when you want a phone number rather than free text |
| Dropdown | A select list | Add at least 2 options so the choice is meaningful |
| Checkbox | A yes/no checkbox | Good for acknowledgements or simple confirmations |
| Date | A date picker | The submitted value must be a valid date |
| File | An image upload field | Best for collecting a photo; keep uploads under 2 MB after processing |
What you can set on each field
Every field needs a clear label. Depending on the field type, you can also set:
- an optional description to help the participant understand the question
- whether the field is required
- placeholder text for input fields
- a list of options for dropdown fields
A form must have at least one field before you can save it.
Edits that affect existing answers
Form layouts are reusable, so a change can affect every Campaign that uses the same layout.
| Change | Practical effect |
|---|---|
| Fixing label text or typos | Safe for readability and does not change the meaning of past answers |
| Deleting a field | Past answers for that field can be lost |
| Changing dropdown choices | Older answers may be harder to compare with new ones |
| Swapping the form on an active Campaign | Past responses may no longer line up with the new form |
Export answers before major edits
Before you delete fields, swap forms, or redesign an active form, export the existing participation form answers first.
Where answers appear
Participation form answers appear in the participant detail view and in the Campaign's participation form exports. Clear, readable labels make those views much easier to work with.
