Twisty section Javascript library to open/close content dynamically
Introduction
This contrib packages in a convenient way the JavaScript library and the CSS file needed to implement Twisty sections.
TwistyContrib is installed by default in TWiki and used by TwistyPlugin.
It is recommended to use the TwistyPlugin as it eases the deployment and use of this contrib.
Usage examples
If the contrib is properly installed (and JavaScript is enabled in your browser) you should see two folding sections below.
<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">
Hamlet is without question the most famous play in the English language. Probably written in 1601 or 1602, the tragedy is a milestone in Shakespeare's dramatic development.
</span>
Generates:
Expand...Hamlet is without question the most famous play in the English language...Collapse...
Hamlet is without question the most famous play in the English language. Probably written in 1601 or 1602, the tragedy is a milestone in Shakespeare's dramatic development.
Skins can customize the color of the twisty placeholder by modifiying the .twistyPlaceholder style.
Some of my TWiki users are impressed by the optical effect of what can be done with 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 copy&pasting 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 can include the text in a verbatim block if you want (like I have done here). Additionally I've added plenty of newlines and spaces to make it readable. This works, and you don't have to care for invalid HTML!
Your Users Write
In any topic, your users can now write things like this:
* *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 behavior of a program, so the keywords of control structures are the most critical components of a program. ...
