To make a field required you must be inside the template editor. Access this by clicking the cog next to a template’s name in your dashboard, then select “Edit this template” from the right-hand menu.
Once there, select the task that you would like to add a required field to by clicking on it.
All Form Fields except for the ‘Hidden’ field can be made required by checking the ‘Required’ checkbox underneath each field.
You can also make a Sub-Checklist required by checking the ‘Required (All sub-tasks)’ checkbox under the Sub-Checklist.
Once selected, you will be unable to proceed beyond that specific task without completing all required fields and/or sub-checklists when running a checklist.
