Preview mode

Preview in the workspace toolbar opens the current draft — including unpublished, even unpublishable, changes — in a full-screen overlay.

What you’re looking at is not a simulation: it is the actual <forms-engine> web component, the same code your website embeds, mounted directly on the draft definition instead of a published version. Rules, answer clearing, required-field gating, validation messages — everything behaves exactly as it will live, because it is the live renderer. The editor is the embed’s first consumer.

What’s different from a live embed:

• Nothing is saved. No response is created, no answers are sent, no session is stored. You can preview a hundred times and the responses browser stays empty.
• File selections stay local. Files you pick render as rows tagged preview — not uploaded; they are never sent, so server-side content verification doesn’t run here. (The overlay’s subtitle says exactly this.)

Reset restarts the run from a blank first screen; closing and reopening does the same. Preview always starts from the beginning — there’s no “jump to the screen I’m editing”.

Use it as the tight loop for rule-building: set up a visibility rule, open preview, type the triggering answer, watch the follow-up appear — and watch its answer get cleared when you change the trigger back.
