*A "twisty" is an interface toggle control to show and hide content.*

!TwistyPlugin gives you several options to control the appearance of a twisty:
   * use link text or buttons
   * position an icon left or right
   * remember the state at the next visit of the page
   * start the Twisty open or closed
   * start the Twisty open or closed for the first visit
   * use a span or div for the content
   * set a class for the content span or div

Twisty has a fallback mechanism in case !JavaScript is not available: all content is displayed and the control buttons are hidden.

%TOC{title="On this page:"}%

---++ Usage examples
---+++ Triad
A Twisty consists of 3 elements:
   1 Show button
   1 Hide button
   1 Collapsing content ('Toggle')
   
The typical !TwistyPlugin triad will look like this (pseudo code):

<verbatim>
%TWISTYSHOW{}% %TWISTYHIDE{}%
(there may be other things between buttons and content)
%TWISTYTOGGLE{}% my content %ENDTWISTYTOGGLE%
</verbatim>

---+++ Shorthand

The Twisty triad is conveniently packed into shorthand =%<nop>TWISTY{some parameters}% Collapsing content %<nop>ENDTWISTY%=:

<verbatim>
%TWISTY{}%
my twisty content
%ENDTWISTY%
</verbatim>

Will generate:

%TWISTY{}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

You may have noticed that no parameters are passed to =%<nop>TWISTY{}%= but the show and hide links _do_ have text! The default values are fetched from plugin settings =TWISTYSHOWLINK= and =TWISTYHIDELINK=, see [[#PluginSettings][Plugin Settings]] below.


---+++ Twisty with icons
We will use =mode="div"= to put the collapsing content below the button (the default mode is ="span"=).

<verbatim>
%TWISTY{
mode="div"
showlink="Show..."
hidelink="Hide"
showimgleft="%ICONURLPATH{toggleopen-small}%"
hideimgleft="%ICONURLPATH{toggleclose-small}%"
}%
my twisty content
%ENDTWISTY%
</verbatim>

It will look like this:

%TWISTY{
mode="div"
showlink="Show..."
hidelink="Hide"
showimgleft="%ICONURLPATH{toggleopen-small}%"
hideimgleft="%ICONURLPATH{toggleclose-small}%"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

To put icons at the right side, write
<verbatim>
%TWISTY{
mode="div"
showlink="Show&nbsp;"
hidelink="Hide&nbsp;"
showimgright="%ICONURLPATH{toggleopen-small}%"
hideimgright="%ICONURLPATH{toggleclose-small}%"
}%
my twisty content
%ENDTWISTY%
</verbatim>

%TWISTY{
mode="div"
showlink="Show&nbsp;"
hidelink="Hide&nbsp;"
showimgright="%ICONURLPATH{toggleopen-small}%"
hideimgright="%ICONURLPATH{toggleclose-small}%"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%



---+++ Make it remember
To store the last state in a FOSWIKIPREF cookie, add the parameter =remember="on"=.%BR%
To test this, reload the page after toggling.

<verbatim>
%TWISTY{
showlink="Show..."
hidelink="Hide"
remember="on"
}%
my twisty content
%ENDTWISTY%
</verbatim>

%TWISTY{
showlink="Show..."
hidelink="Hide"
remember="on"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

If a Twisty state has been stored in a FOSWIKIPREF cookie before, it can be cleared by using =remember="off"=:

<verbatim>
%TWISTY{
showlink="Show..."
hidelink="Hide"
remember="off"
}%
my twisty content
%ENDTWISTY%
</verbatim>

%TWISTY{
showlink="Show..."
hidelink="Hide"
remember="off"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

*NOTE:* Twisty ids are generated automatically. If you need control over exactly _which_ Twisty should be remembered, add the parameter =id=:

<verbatim>
%TWISTY{
id="currentCustomerList"
showlink="Show..."
hidelink="Hide"
remember="on"
}%
my customer list
%ENDTWISTY%
</verbatim>

Note that =id= sets a sitewide cookie. To create a unique id, add topic or web macros:
<verbatim>
id="%WEB%_%TOPIC%_currentCustomerList"
</verbatim>



---+++ Make it obey
To let the Twisty start with its content folded open, add parameter =start="show"=. 

<verbatim>
%TWISTY{
showlink="Show..."
hidelink="Hide"
start="show"
}%
my twisty content
%ENDTWISTY%
</verbatim>

%TWISTY{
showlink="Show..."
hidelink="Hide"
start="show"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

Likewise use =start="hide"= to start with hidden content.

<verbatim>
%TWISTY{
showlink="Show..."
hidelink="Hide"
start="hide"
}%
my twisty content
%ENDTWISTY%
</verbatim>

%TWISTY{
showlink="Show..."
hidelink="Hide"
start="hide"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%



---+++ Make it obey only the first time
To let the Twisty start with its content folded open the first time the visitor sees the Twisty, add the parameter =firststart="show"=.
If =remember="on"= is used, subsequential visits to the page will display the Twisty according the cookie setting.

<verbatim>
%TWISTY{
showlink="Show..."
hidelink="Hide"
firststart="show"
}%
my twisty content
%ENDTWISTY%
</verbatim>

%TWISTY{
showlink="Show..."
hidelink="Hide"
firststart="show"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%


---+++ Other use: hide interface parts in case of no !JavaScript

You can use Twisty to show interface elements that should only be visible with !JavaScript enabled. For instance the textbox control buttons in the edit screen need !JavaScript to work. If a visitor does not have !JavaScript on it would not make sense to show these buttons.

Put the "JavaScript content" in an almost bare bones Twisty. Write =showlink="" hidelink=""= to not display any default link texts.

<verbatim>
%TWISTY{
link=""
noscript="hide"
start="show"
}%
<input type="submit" class="foswikiButton" value="You surely have !JavaScript" />
%ENDTWISTY%
</verbatim>

%TWISTY{
link=""
noscript="hide"
start="show"
}%
<input type="submit" class="foswikiButton" value="You surely have !JavaScript" />
%ENDTWISTY%

Do not forget to set =start="show"= to show the Twisty content at all. 

When !JavaScript is off, the button should be invisible.

This code will show the button when !JavaScript is off:

<verbatim>
%TWISTY{
link=""
start="show"
}%
<input type="submit" class="foswikiButton" value="You might have !JavaScript" />
%ENDTWISTY%
</verbatim>

%TWISTY{
link=""
start="show"
}%
<input type="submit" class="foswikiButton" value="You might have !JavaScript" />
%ENDTWISTY%



---+++ Styling the Twisty
Use parameter =class= to style the content div or class:

<verbatim>
%TWISTY{
mode="div"
showlink="Show..."
hidelink="Hide"
class="foswikiHelp"
}%
my twisty content
%ENDTWISTY%
</verbatim>

Generates: %BR%
%TWISTY{
mode="div"
showlink="Show..."
hidelink="Hide"
class="foswikiHelp"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%


---+++ Styling the Twisty link or button
Use parameter =linkclass= to style the twisty links:

<verbatim>
%TWISTY{
mode="div"
showlink="Show..."
hidelink="Hide"
linkclass="foswikiButton"
}%
my twisty content
%ENDTWISTY%
</verbatim>

Generates: %BR%
%TWISTY{
mode="div"
showlink="Show..."
hidelink="Hide"
linkclass="foswikiButton"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%


---+++ Twisty headers
To be able to use header tags like =&lt;h2&lt;=, use the properties =prefix= and =suffix=. Because we have identical show and hide links we can use the shorthand property =link=.

<verbatim>
%TWISTY{
prefix="<h4>"
mode="div"
link="Twisty Header"
showimgleft="%ICONURLPATH{toggleopen}%"
hideimgleft="%ICONURLPATH{toggleclose}%"
suffix="</h4>"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%
</verbatim>

Will create:

%TWISTY{
prefix="<h4>"
mode="div"
link="Twisty Header"
showimgleft="%ICONURLPATH{toggleopen}%"
hideimgleft="%ICONURLPATH{toggleclose}%"
suffix="</h4>"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

If you don't use images, there is an easier way to create a twisty header:

<verbatim>
%TWISTY{
mode="div"
showlink="<h4>&#9658; Details</h4>"
hidelink="<h4>&#9660; Details</h4>"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%
</verbatim>

Will create:

%TWISTY{
mode="div"
showlink="<h4>&#9658; Details</h4>"
hidelink="<h4>&#9660; Details</h4>"
}%
%GREEN% my twisty content %ENDCOLOR%
%ENDTWISTY%

---+++ 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=.

<verbatim>
<button class="twistyExpandAll foswikiButton">Expand all</button> &nbsp; <button class="twistyCollapseAll foswikiButton">Collapse all</button>
</verbatim>

Creates these controls:

<button class="twistyExpandAll foswikiButton">Expand all</button> &nbsp; 
<button class="twistyCollapseAll foswikiButton">Collapse all</button>

When you want to use links, write:

<verbatim>
#VarTOGGLE

<a href="#TOGGLE" class="twistyExpandAll">Expand all</a> &nbsp; 
<a href="#TOGGLE" class="twistyCollapseAll">Collapse all</a>
</verbatim>


#VarTOGGLE

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


---++ Special syntax: format tokens
If you use other macros inside TWISTY parameters chances are it will mess up the macro, or the rendered html. Use format tokens to 'delay' rendering of these variables until the Twisty parameters are parsed.

The format tokens are the same as with %SYSTEMWEB%.FormattedSearch:

| *Escape:* | *Expands To:* |
| =$n= or =$n()= | New line. Use =$n()= if followed by alphanumeric character, e.g. write =Foo$n()Bar= instead of =Foo$nBar= |
| =$nop= or =$nop()= | Is a "no operation". |
| =$quot= | Double quote (="=) |
| =$percnt= | Percent sign (=%=) |
| =$dollar= | Dollar sign (=$=) |


For example, to show an icon inside the link, do not write:
<verbatim>
link="%Y%"
</verbatim>

but use format tokens:

<verbatim>
link="$percntY$percnt"
</verbatim>

... to get:

%TWISTY{
mode="div"
link="$percntY$percnt"
showimgleft="%ICONURLPATH{toggleopen-small}%"
hideimgleft="%ICONURLPATH{toggleclose-small}%"
}%
my twisty content
%ENDTWISTY%

Or a more complex example using %SYSTEMWEB%.SpreadSheetPlugin; do not write:

<verbatim>
link="Count: (%CALC{"$GET(infoCount)"}%)"
</verbatim>

but use format tokens:

<verbatim>
link="Count: ($percntCALC{$quot$dollarGET(infoCount)$quot}$percnt)"
</verbatim>

---++ Working with other Javascript libraries

If you want to use a different Javascript library than the default Foswiki Javascripts, add to the skin path:
   * =jquery= to use [[http://jquery.com/][JQuery]] 
      * For example, append to the url: =?skin=jquery,nat= %BR%
      or write: =Set SKIN = jquery,nat=
      * For this, Foswiki:Extensions/JQueryPlugin needs to be installed
   * =dojo= to use [[http://jquery.com/][JQuery]] 
      * For example, append to the url: =?skin=dojo,pattern= %BR%
      or write: =Set SKIN = dojo,pattern=
      * For this, Foswiki:Extensions/DojoToolkitContrib needs to be installed
