The TopMenuSkin adds pulldown menus to the 
PatternSkin.

 Tob Bar and Menu Structure 
  
NOTE: The skin is designed to incorporate the "you are here" breadcrumb into the pulldown menus:
  "Home" menu => "Web" menu => List of parent topics, if any (shown as "P"s) => Current topic ("View" menu).
 Web-specific Menu-Bars 
The 
TopMenuSkinDefaultWebTopMenu defines the default menu structure used in any web. A WebTopMenu topic in a web can redefine the default menu structure. If the WebTopMenu topic is missing in a web, create one with content of 
_default.WebTopMenu and customize it. Bullets must be of format 
[[...][...]] or 
<a href="...">...</a>, and may not contain any text next to the link.
To preserve the "you are here" breadcrumb, it is important to add additional pulldown menus 
after the INCLUDE of %SYSTEMWEB%.TopMenuSkinTopicMenu. The top level menu-bar should have this structure:
 
-  INCLUDE of %SYSTEMWEB%.TopMenuSkinHomeMenu
-  Current Web menu
-  INCLUDE of %SYSTEMWEB%.TopMenuSkinTopicMenu
-  Additional pulldown menu(s) as needed (optional)
Example WebTopBar menu structure with additional "Bugs" pulldown menu:
%INCLUDE{%SYSTEMWEB%.TopMenuSkinHomeMenu}%
   * [[%BASEWEB%.%HOMETOPIC%][<img src="%ICONURL{web-bg}%" border="0" alt="" width="16" height="16" style="background-color:%WEBBGCOLOR%" /> <nop>%MAKETEXT{"[_1] Web" args="%BASEWEB{format="$current"}%"}% %ICON{menu-down}%]]
      * [[%SCRIPTURLPATH{"view"}%/%BASEWEB%/WebCreateNewTopic?topicparent=%BASETOPIC%][ %ICON{"newtopic"}% %MAKETEXT{"Create New Topic"}%]]
      * [[%BASEWEB%.WebTopicList][ %ICON{"index"}% %MAKETEXT{"Index"}%]]
      * [[%BASEWEB%.WebSearch][ %ICON{"searchtopic"}% %MAKETEXT{"Search"}%]]
      * [[%BASEWEB%.WebChanges][ %ICON{"changes"}% %MAKETEXT{"Changes"}%]]
      * [[%BASEWEB%.WebNotify][ %ICON{"notify"}% %MAKETEXT{"Notifications"}%]]
      * [[%BASEWEB%.WebRss][ %ICON{"feed"}% %MAKETEXT{"RSS Feed"}%]]
      * [[%BASEWEB%.WebStatistics][ %ICON{"statistics"}% %MAKETEXT{"Statistics"}%]]
      * [[%BASEWEB%.WebPreferences][ %ICON{"wrench"}% %MAKETEXT{"Preferences"}%]]
%INCLUDE{%SYSTEMWEB%.TopMenuSkinTopicMenu}%
   * [[BugTracker][%ICON{bug}% Bugs %ICON{menu-down}%]]
      * [[NewReport][Create bug report]]
      * [[OpenBugs][Open bugs]]
      * [[ConfirmedBugs][Confirmed bugs]]
      * [[FixedBugs][Fixed bugs]]
 Use Menu-Bars in Topics 
A menu-bar can be added anywhere in a topic: 
-  Include the "TWiki.TopMenuSkin" topic - this pulls in the CSS and JavaScript needed for the menu-bar.
-  Create a nested bullet list with links: 
-  The top level bullets define the menu-bar items. Bullets with/without links are supported.
-  Second level bullets define the pulldown options within a menu-bar item. 
-  A second level bullet must contain exactly one link (format [[...][...]]or<a href="...">...</a>) without any text next to the link.
 
-  Third level bullets are not supported.
 
-  Enclose the bullet list with a <div class="twTopMenuTab">tag.
Example:
%INCLUDE{"%SYSTEMWEB%.TopMenuSkin"}%
<div class="twTopMenuTab">
   * [[WebHome][%ICON{home}% Home %ICON{menu-down}%]]
      * [[WebNotify][Subscribe]]
      * [[WebStatistics][Statistics]]
   * [[WebSearch][%ICON{searchtopic}% Search %ICON{menu-down}%]]
      * [[WebSearchAdvanced][Advanced search]]
      * [[SearchHelp][Search help]]
</div>

NOTE: The pulldown menus only work if the 
TWiki:Plugins/JQueryPlugin
 is installed and enabled.
 Read-Only Skin Mode 
This skin and the 
PatternSkin support a read-only mode. This is mainly useful if you have TWiki application pages or dashboards where you do not want regular users to change content. The read-only mode is enabled with a READONLYSKINMODE preferences setting set to 1. Details in 
PatternSkinCustomization#ReadOnlySkinMode.
 CSS and JavaScript 
This section defines the CSS and JavaScript used by the TopMenuSkin; 
View Raw to see the source. Some additional CSS is defined in 
templates/vewi.topmenu.tmpl
 Create Your Own Look 
This skin is based on 
PatternSkin, and the same rules for customization apply.
The TopMenuSkin disables the sidebar and activates a different top bar in 
twiki/templates/view.topmenu.tmpl. Details in 
PatternSkinCustomization and 
PatternSkinCssCookbook.
The top bar 
TopMenuSkinTopBar (with menu bar, logo and search boxes) can be cloned using same topic name and customized per web.
 Add a Sidebar 
If you want a sidebar in addition to the top bar, define a WEBLEFTBAR setting with the name of the topic to include as the sidebar. This can be done in a WebPreferences for the whole web or in a topic. Example:
  
 Add Breadcrumbs 
The TopMenuSkin incorporates "you are here" breadcrumbs in the pulldown menu, such as 
"Home > Main web > P > P > View. The P's indicate the parent topic(s). If you prefer the old verbose breadcrumbs you can enable it with the following preferences setting:
  
 Fixed Menu-Bar 
The FIXEDTOPMENU preferences setting determines if the menu-bar is fixed or auto-hidden. If set to on, the menu-bar is always visible at the top, regardless of the window scroll position. If off, the menu-bar hides when scrolled, and can be shown by hovering over 

 - the gray TWiki icon. 
 
 Installation 
This skin is pre-installed. TWiki administrators can upgrade the skin as needed on the TWiki server.
