Use the Confluence Add-On Scaffolding Forms & Templates

If you need forms, living templates, or forms in templates, use Scaffolding Forms & Templates

Review the Scaffolding for Confluence documentation. The Tutorials and Guide are especially helpful.
Use Cases - include examples with Comala Workflows data
Scaffolding includes many macros to create forms. See the Macro Reference guide for details.
Be aware of how pages with scaffolding behave with the Confluence mobile app: they do not display the values from the Scaffolding forms and point to a "use desktop version" link which brings you to a webpage with the Confluence page. The values from Scaffolding are displayed in the website.
