Cache DCE frontend plugin 

DCE generates the frontend plugin registration automatically when its code cache is rebuilt. This option controls whether DceController::showAction is registered as cacheable or non-cacheable for this DCE.

Direct output 

With this option enabled you bypass fluid_styled_content. Instead of using lib.contentElement, the DCE controller action is used directly. This reduces rendering overhead and removes wrappings defined by Fluid Styled Content, for example <div id="c123" ...>.

This option is enabled by default, separately for each DCE.

FlexForm label 

Defines the text displayed in the content element:

Enable media tab in backend 

This option is only available when EXT:fluid_styled_content is installed. If this option is activated a tab with media (FAL) field is shown in the backend.

You can access the {contentObject.assets} or {contentObject.media} variable in a Fluid template. It contains an array of \TYPO3\CMS\Core\Resource\FileReference.

Enable categories tab in backend 

If this option is activated a tab with category picker is shown in the backend.

You can access {contentObject.categories} variable in Fluid template. It contains an array of \TYPO3\CMS\Extbase\Domain\Model\Category.

DCE palette fields 

This is a list of fields which should be shown in the head area of this DCE in the backend.

Fluid layout and partial root path 

Layouts and partials are a part of Fluid templates and are used to avoid redundancies and keep the code cleaner.

Here you can define Fluid templates folders where to find the layouts and the partials.

With TypoScript you can also set up multiple folder paths for layouts and partials with priority order.
