Hierarchical navigation menus

Description

With release of Trac 0.11, existing items can be ​customized on the main and meta navigation bars. This plugin extends that functionality to:

• Add items to navigation menus.
• Hierachical organization, for example using ​Superfish.

See it in action: ​http://code.optaros.com/trac/oforge/

Note: CSS modifications might be needed to fit your Trac theme.

Installation

To install this plugin, follow these steps:

1. Install the plugin following the steps in the ​Trac Documentation.
2. Add tracmenus.* = enabled to the [components] section of trac.ini or enable via WebAdmin.
3. Restart the Trac server.
4. Proceed to the Configuration section.

Configuration

As usual, configuration takes place in the trac.ini file. Most interesting things first - they are to be found in the [mainnav] section: Here you set up your menu items. Syntax is: <item_name>.<property> = <value> - where <item_name> is either the already existing handler (e.g. "wiki" for the wiki item, "tickets" for the tickets, "newticket" for the "New Ticket" item and so on) - or a term which must not exist for a brand new item to be introduced (as the "Team Tools" in the Examples section). A special case is top to make a new item appearing on top level.

Defining menus in the [mainnav] and [metanav] sections

The available properties and their possible values are:

Property	Description	Example value
enabled	Must be set to 1 for self defined items to be shown. Can be set to 0 to (temporarily) disable an item.	1
hide_if_no_children	Don't display this (sub) menu if it has no children (e.g. the current user lacks the privileges for all sub-items)	1
href	Where the item should link to	/report/1
label	What should be written on the "button"	Team Tools
order	Move an item to the left/right. By default, all items have an order of 999 (who will ever reach 999 items must have done something wrong, really!). Use values from 1..999 to define positions. Use a negative value for an item you want to make sure it always comes first - and a value larger than 999 if it sould always come last.	5
parent	Make the item a sub-item to the one mentioned as value	top
path_info	String to be matched with the request path info to decide whether a menu item should be displayed. Useful for context dependent items (e.g. in the ctxnav)	/wiki
perm	For items like reports, hide_if_disabled does not work, since this is no component. Though, it should not be displayed if it is not available. So you can handle this by defining the required permission.	REPORT_VIEW

Menu options

• inherit: Useful when a menu should receive items from another menu

  # dummy example - add mainnav items to context menu.
  [ctxtnav]
  inherit= mainnav
  

Defining behaviour in the [menu-custom] section

Although the defaults are fine, you can customize the behavior of MenusPlugin. The syntax for the options is similar to a key-value pair: <option> = <value>. Available options are:

Option	Description	Default
managed_menus	Which menus should be maintained by the plugin.	mainnav,metanav
serve_ui_files	Whether the required UI files, ie *.js and *.css files, should be linked into the page. Boolean value.	1

The serve_ui_files option you will only need to override if you want to apply your own styles and need to suppress the original ones for this.
