TabbedBrowsing < Main

Tags: view all tags
This page provided tabbed browsing capabilities.  It is based on [[http://twiki.org/cgi-bin/view/Sandbox/TabbedBrowsing][This page from Twiki itself]].  

<noautolink>
<verbatim>
%CALC{$SET(tabs, SomeTopicSummary:Summary, SomeTopicDiscuss:Discuss this page, SomeTopicForm:Modify form)}%
%INCLUDE{Main.TabbedBrowsing}%
</verbatim>
</noautolink>

The above code would get rendered like this (links deactivated), assuming that the user is currently viewing the !SomeTopicDiscuss topic:

<div id="tab_list">
  <ul>
    <li><a href="#">Summary</a></li>
    <li id="tab_current"><a onClick="return false" href="#">Discuss this page</a></li>
    <li><a href="#">Modify form</a></li>
  </ul>
  <span class="no_tab"><a href="#"><img src="%PUBURL%/%TWIKIWEB%/TWikiDocGraphics/help.gif"/></a></span>
</div>
<br style="clear:both" />

*NOTES*:
   * The tab associated with the current topic is automatically recognized and properly highlighted.
   * The topics in the tabs don't need to exist. The first person to click on the tab, gets to create it (same as TWiki links, but without the !TopicDoesNotExist icon).
      * If you do choose to create a seprarate tab definition topic, you might also want to define the following =editlink= variable: <br>
        =%<nop>CALC{$SET(tabs, ...)}%= <br>
        =%<nop>CALC{$SET(editlink, %<nop>TOPIC%)}%= <br>
        =%<nop>INCLUDE{Main.StandardTabs}%= <br>
        This will put a %PUBURL%/%TWIKIWEB%/TWikiDocGraphics/edittopic.gif button right before the %PUBURL%/%TWIKIWEB%/TWikiDocGraphics/help.gif button, pointing to the tab definition page.
   * The tabs look best at the top of the page, but you can place them whereever you want.
   * The tab graphics point to [[http://www.alistapart.com/articles/slidingdoors/ this site]]. These need to be modified in a way that fits in with the current skin.
   * Most of the magic is done by TWiki.SpreadSheetPlugin along with some nifty CSS code _borrowed_ from [[http://www.alistapart.com/articles/slidingdoors/ this site]] (see code below in raw mode).
