-Example: Creating hierarchical menus of custom links
-----------------------------------------------------
-
-By default the HMENU object is designed to create menus from pages in
-TYPO3. Such pages are represented by their page-record contents.
-Usually the "title" field is used for the title and the "uid" field is
-used to create a link to that page in the menu.
-
-However the HMENU and sub-menu objects are so powerful that it would
-be very useful to use these objects for creating menus of links which
-do not relate to pages in TYPO3 by their ids. This could be a menu
-reflecting a menu structure of a plugin where each link might link to
-the same page id in TYPO3 but where the difference would be in some
-parameter value.
-
-First, this listing creates a menu in three levels where the first two
-are graphical items:
-
-.. code-block:: typoscript
-   :linenos:
-
-   # ************************
-   # CUSTOM MENU
-   # ************************
-   lib.custommenu = HMENU
-   lib.custommenu {
-      special = userfunction
-      special.userFunc = Vendor\MyExtension\Userfuncs\CustomMenu->makeMenuArray
-
-      1 = TMENU
-      1.wrap = <ul class="level-1">|</ul>
-      1.NO = 1
-      1.NO {
-         wrapItemAndSub = <li>|</li>
-      }
-
-      2 = TMENU
-      2.wrap = <ul class="level-2">|</ul>
-      2.NO = 1
-      2.NO {
-         wrapItemAndSub = <li>|</li>
-      }
-
-      3 = TMENU
-      3.wrap = <ul class="level-3">|</ul>
-      3.NO = 1
-      3.NO {
-         wrapItemAndSub = <li>|</li>
-      }
-   }
-
-The menu looks like this on a web page:
-
-.. figure:: /Images/ManualScreenshots/FrontendOutput/Hmenu/ContentObjectsHmenuExampleMenu.png
-   :alt: Output of the example menu.
-
-The TypoScript code above generates this menu, but the items do not
-link straight to pages as usual. This is because the *whole* menu is
-generated from this array, which was returned from the function
-"makeMenuArray" called in TypoScript line 5+6 :

-Notice how the array contains "fake" page-records which has *no* uid
-field, only a "title" and "\_OVERRIDE\_HREF" as required and some
-other fields as it fits.
+..  _hmenu-special-userfunction-examples:
 
-- The first level with items "Contact" and "Products" contains "title"
-  and "\_OVERRIDE\_HREF" fields, but "Contact" extends this by a
-  "\_SUB\_MENU" array which contains a similar array of items.
+Example: Set a userFunc
+~~~~~~~~~~~~~~~~~~~~~~~
 
-- The first item on the second level, "Offices", contains a field called
-  "\_OVERRIDE\_TARGET". Further the item has its state set to "ACT"
-  which means it will render as an "active" item (you will have to
-  calculate such stuff manually when you are not rendering a menu of
-  real pages!). Finally there is even another sub-level of menu items.
