<span id="demo1hide" class="twistyTrigger twistyHidden"><button class="twikiButton"> Fold </button></span>
<span id="demo1toggle" class="twistyContent twistyMakeHidden">

Twisty with placeholder text

<span id="demo2show" class="twistyTrigger twistyMakeVisible"><a href="#">Expand...</a> <span class="twistyPlaceholder">Hamlet is without question the most famous play in the English language...</span></span>
<span id="demo2hide" class="twistyTrigger twistyHidden"><a href="#">Collapse...</a></span>
<span id="demo2toggle" class="twistyContent twistyMakeHidden">

Twisty made easy

Manual written by Harald Joerg. Examples require Spreadsheet Plugin to work (installed by default).

Some of my TWiki users are impressed by the optical effect of what can be done with TWiki:Plugins.TwistyPlugin - and they keep asking me: "How do I do that? I don't understand the documentation, and I don't understand the raw text of your topics!"

They indeed have a point here. The docs aren't easily understood. It isn't easy to pick all the variables needed from a single example, and just copypasting sometimes fails in embarrassing ways if non-unique id attributes are present in a topic. Maybe it is easy for a power user, but it surely isn't easy enough. There ought to be a way to make it easier.

Well, here you are.

Just set a couple of site preferences, and your users will immediately understand your examples and start writing their own twisties. And what's more: They'll do so in a consistent way, across all your topics in all webs.

You Write

   * Set FLIP = <span id="twid_%CALC{$SETM(twisty_id, + 1)$GET(twisty_id)}%show" class="twistyTrigger twistyMakeVisible">
       <a href="#">more...</a>
     </span>
     <span id="twid_%CALC{$GET(twisty_id)}%hide" class="twistyTrigger twistyHidden">
       <a href="#">close</a>
     </span>
     <div id="twid_%CALC{$GET(twisty_id)}%toggle" class="twistyContent twistyMakeHidden">
   * Set FLOP = </div>

Your Users Write

   * *Brace and parenthesize in K&R style* 
     %FLIP% 
     When setting out a code block, use the K&R style of bracketing.  
     That is, place the opening brace at the end of the construct that controls the block. ... 
     %FLOP%
   * *Separate your control keywords from the following opening bracket* 
     %FLIP% 
     Control structures regulate the dynamic behaviour of a program, so the keywords 
     of control structures are the most critical components of a program. ... 
     %FLOP%

All on, all off

You can toggle all Twisties on or off at once by putting a link or button on the page with class twistyExpandAll or twistyCollapseAll.

<button class="twistyExpandAll twikiButton">Expand all</button> 
<button class="twistyCollapseAll twikiButton">Collapse all</button>

Creates these controls:

Expand all Collapse all

When you want to use links, write:

#VarTOGGLE

<a href="#TOGGLE" class="twistyExpandAll">Expand all</a> 
<a href="#TOGGLE" class="twistyCollapseAll">Collapse all</a>

Expand all Collapse all

Contrib Info

TwistyContrib

Summary

This contrib packages in a convenient way the Javascript library and the CSS file needed to implement TWisty Sections.

To use the libraries, you must place the following scriplet either in the head section of the page (by modifying the TWikiSkins) or putting it somewhere in the topic:

<style type="text/css" media="all">
@import url("%PUBURLPATH%/TWiki/TwistyContrib/twist.css");
</style>

<script type="text/javascript" src="%PUBURLPATH%/TWiki/TwistyContrib/twist.js"></script>

It's recommended to use the TWiki:Plugins.TwistyPlugin, as it eases the deployment and use of this contrib.

Caution: If the previous scriplet is put in the HEAD section of the page or the TWiki:Plugins.TwistyPlugin is used, it won't work if the <body onload=""> manager is set by the skin. Check the twist.js file for an idea on how to register an eventmanager for the onload event without overwriting the previous one.

This Contrib should work in all versions of TWiki. It has been tested against TWiki:Codev.CairoRelease and TWiki:Codev.DakarRelease.

Customization

Skins can customize the color of the twisty placeholder by modifiying the .twistyPlaceholder style.

Settings

• Name of the perl package
  • Set STUB = TWiki::Contrib::TwistyContrib

• One line description:
  • Set SHORTDESCRIPTION = Placeholder for the twisty javascript library.

Installation Instructions

• Download the ZIP file from the Plugin web (see below)
