Regions are editable content and code snippets which you can re-use everywhere on your website.
Mange region fields in the field-manager and re-use them in the region template code.
Define a template code. You've access to every region field defined in the region field-manager. Every template will be parsed on the server and the result will be returned as a string value.
You can also write PHP code for e.g. looping over field values.
Region Entry Form
Content editors will get an easy to use form to manage the region data.
