AcMenu provides an accordion menu which lists the content of namespaces in a tree-like format. The tree is built starting from the namespace where the AcMenu's syntax lives till the very end namespace.

This plugin respects the ACL rules and, moreover, the sneaky_index and hidepages options that come with your DokuWiki configuration.

Search and install ​the plugin using the Extension ​Manager. Refer to Plugin Installation Instructions on how to install plugins manually.

In the sidebar page, use the syntax:

<acmenu>

Just some screenshots to give you an overall idea of the final result.

Suppose you want to create a sub-wiki in your main one, independent from it, as follows:

+--sidebar.txt
+--start.txt
+--products
|  +--start.txt
|  +--product_a.txt
+--services
|  +--start.txt
|  +--service_a.txt
+--branch
   +--sidebar.txt
   +--start.txt
   +--private
   |  +--start.txt
   |  +--confidential.txt
   +--products
   |  +--start.txt
   |  +--product_b.txt
   +--services
      +--start.txt
      +--service_b.txt

Then you can populate each sidebar.txt in the following manner:

• in :sidebar.txt

  <acmenu>

• in :branch:sidebar.txt

  [[..:start| Go Back]]
  <acmenu>

  where the Go Back link is made according to the namespaces criterion.

When a visitor is in :start.txt, the plugin shows the complete namespace tree collapsed except the namespace in which the sidebar.txt, with AcMenu's syntax, is.

If the visitor decides to open the sub-wiki :branch, the AcMenu plugin shows only its sidebar.

To deny access to certain namespaces or pages, the appropriate rule in the ACL management must be set. In addition, it's possible to conceal those namespaces for which the visitor has no read permission defining the sneaky_index option in your Configuration Manager.

Furthermore, it's possible to hide the sidebar.txt and the start.txt pages¹⁾ using the hidepages option in your Configuration Manager:

(?<=:)sidebar$|(?<=.:)start$|other-matches

The following image is the behaviour of the AcMenu plugin from the perspective of a user registered.

Since this plugin uses cookies to remember the pages visited (they are automatically deleted as soon as the window browser is closed) if the visitor comes back to :start.txt every namespace untoggled will remain so.

The order in which the directory tree is presented is the following:

• first, folders from 0-9A-Za-z
• then, files from 0-9A-Za-z

This means that, if the option useheading is enabled, it's possible to force the order of files using a progressive numeration in the first heading of each file.

Note also that the startpage is intentionally always kept on top of its menu and it's never renamed with its first heading, in order to provide a visual reference for the navigation.

Symptom: AcMenu isn't keeping unfolded any previously opened namespace.

Possible solution: be sure that JavaScript and cookies are enabled in your browser, otherwise AcMenu forgets the previously namespaces untoggled whenever a page is loaded.
