A Form Builder project is one form, built from your project's Build tab: a linear, reorderable list of fields rather than a canvas, since a form's structure is naturally a straight list of questions, not a branching graph.
Adding a field
Click any field type at the bottom of the Build tab to add it to the end of your form. Click a field in the list to select it and edit its Label, whether it's Required, and any type-specific settings (like its options) in the inspector on the right.
Reordering and removing
Drag a field by its handle to reorder it, or use the ↑/↓ buttons and the delete button if you'd rather not drag.
Showing a field only when another field has a certain answer
Open a field's Conditional Visibility setting in the inspector to show it only when another field earlier in the form equals a value you choose, useful for follow-up questions that only make sense after a specific answer. A field hidden this way is skipped entirely for that respondent, it isn't submitted as empty.
Splitting a long form into pages
Turn on Split into multiple pages in your project's Settings, then every Section Break field in your form becomes a page break: respondents see Next/Back buttons and a progress bar instead of one long scroll, and any Required field on a page must be filled in before Next is enabled. Your form is still submitted once, at the end, exactly the same responses land in your Responses tab either way.
Live preview
The Build tab includes a live preview of your form exactly as a respondent would see it, updating as you add and edit fields, so you always know what you're about to publish.
Tip: Use a Section Break field to divide a longer form into clearly labeled parts, it renders as a heading with optional supporting text, not a question respondents answer, and doubles as a page break once multi page mode is on.
