# Category Menu A RocketDirectory module can display a category menu. The correct module templates needs to be setup and selected from the module settings. A URL query parameter for the category is used to identify the category that should be displayed. The category URL key is defined in the dependacy file of the AppTheme. *Example of the blog dependancy file for the category url key. (See dependacy documention)* ``` <queryparams list="true"> <genxml> <queryparam>blogcatid</queryparam> <tablename>rocketdirectoryapi</tablename> <systemkey>rocketblogapi</systemkey> <datatype>category</datatype> </genxml> </queryparams> ``` ## Module Template Definition A module template needs to be created on the AppTheme with an entry in the dependancies files. This enables the category menu to be selected from the module settings. *Example of dependancy file template option* ``` <moduletemplates list="true"> <genxml> <file>Categories.cshtml</file> <name>Category Menu</name> </genxml> </moduletemplates> ``` ## Category Menu Template In the "default" sub-folder of the AppTheme the above template needs to be created.
