Forms are custom intake forms attached to your board. External people or team members fill them in, and every submission becomes a task - routed to the right project, tags, and priority via field mapping - with an optional approval queue in between. Typical uses: bug reports, feature requests, client requests, job applications, support intake.
Board admins create and manage forms. Board members (editors) with access to all projects also see the Forms page - they can review submissions, approve or decline them, and message submitters, but not edit the forms themselves. Members restricted to specific projects and guests don't see the page at all - they can still submit through the form link like anyone else.
Free plan: includes 1 form per board and 50 submissions per month. Paid plans are unlimited.

Open the Forms Page
In the board navbar, click the Forms button. You will see the list of all forms on the board with their access mode, submissions count, and pending submissions badge.
Click "New Form"
A new form is created and the form builder opens. A form needs at least one project on the board - submissions become tasks, and tasks live in projects.
Set Up the Basics

In the Form section you can configure:
Add Fields
Build your form in the Fields section - see Form Fields for all field types and Field Mapping for routing answers into task fields. The live preview on the right always shows the form exactly as submitters will see it.
Configure Settings

Share It
Copy the form link and send it to anyone - see Share Form.
All changes are saved automatically as you edit.

With the Interactive layout the public form shows one question per screen with a progress bar - a focused, conversational flow that works great on mobile:
Switch between Classic and Interactive at any time - it's purely presentational, and the live preview follows along.
Each form has an Enabled toggle - in the forms list and in the builder toolbar. A disabled form keeps its configuration and submissions, but its public page shows an "unavailable" screen. Deleting a form permanently removes it along with its submissions and their uploaded files (tasks already created stay on the board).
