Form based page creation allows even inexperienced users to quickly add complete pages in pre-defined formats.

Intuitive in-context editing

It's easy to put content exactly where you want it with concrete5’s wysiwyg editing. To edit an area just point to it and away you go. To add or move content simply drag-n-drop the many different content 'block' types around your page.

Versions and Workflows

Access previous Versions of every page and control which is published making it easy to create draft changes and step back to previous versions.

For teams of contributors Workflows allow Administrators to review and verify changes before they are made live.
