Option Sets can have global settings for things like Media Sources and controlling whether or not dynamic asynchronous XHR calls should occur. The visual Settings that display in the browser, can also have sub-sets that serve to keep things organized.

Global Settings

The followng control individual settings and grouping for an Element in a Fred-powered page.


Set to true to cause XHR requests to render the Element through both the Twig and MODX parsers. The element also re-renders through both the Twig and MODX parser when you change element settings. This means you can have dynamic content that references other pages within a Fred page using MODX Snippets. Default: false.


Name of the Media Source to use for Finder. Multiple Names can be passed separated by comma ,.


Name of the Media Source to use for Image fields. Multiple Names can be passed separated by comma ,. This option overrides mediaSource.


Settings are made of a JSON array of objects and group objects which provide configuratin controls for Elements. Settings can import sub-sets of settings using a fred-import object.

Settings properties

The following properties apply to all settings, regarless of the types below:

  • name - Name of the setting, can be used as a Twig variable
  • label - Setting's Label, displayed in the Element Settings panel
  • value - A default value
  • type - Type of the setting, see next section

Note: for the best end-user experience, it is a good idea to set a default value so end users have a starting point to work with. Otherwise it may be confusing due to having a blank Element that may not match the preview image when dragging and dropping into pages.
