What are components?
Acquia Cohesion components are a combination of layout and edit forms that you use to create pages and templates.
Acquia Cohesion components are mini templates with custom edit forms. They can be added and combined on the Layout canvas to create new layouts.
Editors can use them to create pages where the content and layout requirements don't fit within a fixed template structure.
Site builders can use them as reusable components within their content templates.
For more detailed information, see the Components area in the user guide.
