You can set up a form using a regular content page layout.
Previously you needed to choose a special form/iframe page layout to do this. We’ve simplified our layouts and have now included forms on regular content pages and removed the old form/iframe page layout.
Adding a form
Add a content page to your site or edit an existing page.
Add a new block and click on the ‘Forms’ tab.
Choose from the range of form blocks that are currently supported.
