The !TopMenuSkin adds pulldown menus to the PatternSkin.

---++ Tob Bar and Menu Structure

   * TopMenuSkinTopBar - top bar with menu bar, logo and search boxes (replacing WebTopBar), can be cloned and customized per web
   * WebTopMenu - bullet list defining menu bar for %WEB% web
   * TopMenuSkinDefaultWebTopMenu - bullet list defining menu bar for webs that do not have a !WebTopMenu topic
      * TopMenuSkinHomeMenu - "Home" pulldown menu with web list, included by !WebTopMenu
      * TopMenuSkinTopicMenu - "Topic" pulldown menu with topic actions, included by !WebTopMenu

__NOTE:__ The skin is designed to incorporate the "you are here" breadcrumb into the pulldown menus:%BR% "Home" menu => "Web" menu => List of parent topics, if any (shown as "P"s) => Current topic ("View" menu).

#WebSpecific
---++ 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 =[<nop>[...][...]]= or =&lt;a href="..."&gt;...&lt;/a&gt;=, 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:
<verbatim>
%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]]
</verbatim>

---++ Use Menu-Bars in Topics

A menu-bar can be added anywhere in a topic:
   * Include the "%SYSTEMWEB%.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 =[<nop>[...][...]]= or =&lt;a href="..."&gt;...&lt;/a&gt;=) without any text next to the link.
      * Third level bullets are not supported.
   * Enclose the bullet list with a =&lt;div class="twTopMenuTab"&gt;= tag.

Example:<verbatim>
%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>
</verbatim>

Renders as:
<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.

#ReadOnlySkinMode
---++ 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 %SYSTEMWEB%.PatternSkinCustomization#ReadOnlySkinMode.

---++ CSS and !JavaScript

This section defines the CSS and !JavaScript used by the !TopMenuSkin; [[%SCRIPTURL{view}%/%WEB%/%TOPIC%?raw=on][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.

#WebLeftBar
---++ 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:

   * <nop>Set WEBLEFTBAR = WebLeftBar

#BreadCrumbs
---++ 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:

   * <nop>Set BREADCRUMBS = 1

#FixedTopMenu
---++ 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 %ATTACHURL%/menu-start.png - the gray TWiki icon.
   * <nop>Set FIXEDTOPMENU = off

---++ Installation

This skin is pre-installed. TWiki administrators can upgrade the skin as needed on the TWiki server.
%TWISTY{
 mode="div"
 showlink="Show details %ICONURL{toggleopen}% "
 hidelink="Hide details %ICONURL{toggleclose}% "
}%

   * Download the ZIP file from the Skin homepage (see below)
   * Unzip ==%TOPIC%.zip== in your twiki installation directory
   * Install TWiki:Plugins/JQueryPlugin and enable it using configure (if not done already)
   * To turn on the skin, write in !Main.TWikiPreferences: %BR%
     =* Set SKIN = topmenu, pattern=
   * [[%SCRIPTURL{"view"}%/%WEB%/%TOPIC%?skin=topmenu,pattern][Test if installed]]
   * *Note* on upgrading existing TWiki:
      * See [[#WebSpecific][Web-specific Menu-Bars]] above on how to retrofit and customize menu-bars.
   * *Note* on using this skin on TWiki-5.1.1 and older:
      * Attach %ATTACHURL%/twiki-help.gif to %SYSTEMWEB%.TWikiDocGraphics.
   * *Note* on using this skin on TWiki-4.2 and 4.3:
      * This skin depends on TWiki 5.0 specific feature =%<nop>WEB{format="$current"}%= to show the current web in the Web menu. To use this skin on TWiki 4.2 or 4.3, remove the parameter from the WEB variable (to show only =%<nop>WEB%=), or apply patch TWikibug:Item6424 (to add the format parameter feature).
      * This skin depends on TWiki 5.0 specific feature =%<nop>ADDTOHEAD{}%= to add style sheets to the HTML head section. Apply patch TWiki:Support.SID-01117 to inline style sheets.
      * Apply patch TWikibug:Item6430 so that Edit and Attach buttons point to the current topic instead of !TopMenuSkinTopBar.
      * Apply patch TWikibug:Item6438 so that breadcrumb links point to the current web instead of the %SYSTEMWEB% web.
      * Attach %ATTACHURL%/menu-down.gif to %SYSTEMWEB%.TWikiDocGraphics.
      * Attach %ATTACHURL%/twiki-gray.gif to %SYSTEMWEB%.TWikiDocGraphics.
      * If you have more than 30 webs, apply TWikibug:Item6429 to limit the number of webs shown in the "Home" menu.
