You only need to adjust the column configuration of your backend\_layout **Restrict certain content element fields** - To allow a limited set of values for content element fields use `allowed.field = [list of comma separated values]` *Examples:* ``` columns { 1 { name = Column with header and textmedia elements colPos = 3 colspan = 6 allowed { CType = header, textmedia } } } ``` ``` columns { 1 { name = Column with News plugin only colPos = 3 colspan = 6 allowed { CType = list list_type = news_pi1 } } } ``` **Combine multiple content element fields** - The example allows multiple content element types (text and list) while restricting plugin types to `news` only. *Example:* ``` columns { 1 { name = A column with restricted list_type and "normal" CType colPos = 3 colspan = 6 allowed { CType = textmedia, list list_type = news_pi1 } } } ``` **Deny certain content element types** - To remove a set of values from content element fields use `disallowed.field = [list of comma separated values]` *Examples:* ``` columns { 1 { name = Column without divider, plain html and table elements colPos = 3 colspan = 6 disallowed { CType = div, html, table } } } ``` ``` columns { 1 { name = Column with header and list, without News plugin colPos = 3 colspan = 6 allowed { CType = header, list } disallowed { list_type = news_pi1 } } } ``` **Limit the number of content elements** - To restrict the number of content elements use `maxitems = [number of elements]` *Example:* ``` columns { 1 { name = Column with one textmedia colPos = 3 colspan = 6 allowed { CType = textmedia } maxitems = 1 } } ``` Known issues ------------ [](#known-issues) ### TypeError [](#typeerror) *count(): Argument #1 ($value) must be of type Countable|array, null given* Content Defender needs the runtime cache to be available. Please ensure that this cache **doesn't use** a \\TYPO3\\CMS\\Core\\Cache\\Backend\\NullBackend backend.
