Conditional logic
Logic makes one form work for different people: skip the questions that don't apply, and route each respondent to the pages that do. There are two kinds, and both are built visually in the form editor.
Show a field conditionally
Any field can carry a visibility condition: show this field only when an earlier field's answer matches. A field with no condition always shows.
The condition must point at a field on a previous page — a field can't depend on an answer from its own page or a later one. A hidden field is simply skipped; nothing is recorded for it.
Branch between pages
Each page can end with fork rules: "if the answer to X is …, go to page Y." When the respondent finishes the page, big checks the rules in order and the first match decides where they go next. Two things to know about targets:
- A rule can jump only forward — to a later page, or straight to submit to end the form early.
- The otherwise path is where everyone goes when no rule matches. If you don't set one, that's just the next page in order.
A page can hold up to 10 fork rules.
What conditions can test
The comparisons available depend on the field type you're testing:
| Field type | Available comparisons |
|---|---|
| Short text, email | equals, doesn't equal, contains |
| Long text | contains |
| Instagram handle | equals, doesn't equal |
| Number, rating | equals, doesn't equal, at least, at most |
| Single choice, dropdown, likert | equals, doesn't equal |
| Multiple choice | none — can't be tested (yet) |
So "rating at most 3 → go to the feedback page, otherwise → submit" works; branching on a multiple-choice answer doesn't.
A worked example
Say you're screening collaborators:
- Page 1 asks "Are you a brand or a creator?" (single choice).
- A fork rule on page 1: brand → page 2 (budget questions); otherwise → page 3 (portfolio questions).
- On page 2, a "Budget" number field with a visibility condition on an earlier answer, shown only when relevant.
- Page 2's exit jumps straight to submit, skipping the creator pages.
One form, two experiences, and nobody sees a question that wasn't meant for them.
