This plugin is based on the inline folding plugin by ta' Lajżar and the slightly changed version thereof by Christopher Smith and Esther Brunner.

(A lot of the work was based on the older hacks by Chris Stoll. This one combines the features of all plugin variants in one.)

If you want to make additional information available that is hidden by default, you have two options with this plugin:

Inline:

This is example ++text | with some of it only shown when you unfold it++. And after that
the text just continues to flow in the same paragraph.

This is example ++text | with some of it only shown when you unfold it++. And after that the text just continues to flow in the same paragraph.

Block:

This is example text.

++++ Title |

| This table | is only shown | when you unfold the block |

{{page>some other wiki page&inline}}

++++

	Inline	Block
Syntax	++title| formatted text ++	++++title| any content ++++
HTML	<span> tag	<div> tag
Can contain formatting
Can contain block elements1)	—
Can be used within a paragraph, table, list, etc.		—

Search and install the plugin using the Extension Manager.

If you install this plugin manually (by copying the directory to the plugins directory) you need to clear DokuWikis cache in order to make this plugin working. Otherwise it won't fold/unfold correctly. To clear the cache open → modify any character → undo → save → close the file <YourDokuWikiRoot>/conf/local.php. This causes DokuWiki to rebuild its cache. The previous is probably true for even more plugins, thus, a general important information.

Alternatively open the configuration page and save it.

To install the plugin manually:

1. download the source to your plugin folder, lib/plugins.
2. extract the downloaded files contents.

That should create a new folder lib/plugins/folded containing all the files required by the plugin.

action.php           action part for making the translated/configured titles available in the JavaScript code
conf                 folder containing the configuration settings and their metadata
conf/default.php     default values for configuration settings
conf/metadata.php    configuration setting metadata used by [[plugin:config|Configuration Manger]]
lang                 folder containing all the localised language folders
lang/xx              xx = language code, there maybe several of these, at least one being en for english
lang/xx/lang.php     language strings for language code "xx"
lang/xx/settings.php configuration prompts used by [[plugin:config|Configuration Manger]]
script.js            JavaScript to handle hiding and revealing of folded content
style.css            styles for folding labels and folded content
open.gif             arrow image pointing right
closed.gif           arrow image pointing down
syntax               folder containing the plugin scripts
syntax/span.php      plugin script for inline folding (++)
syntax/div.php       plugin script for block folded (++++)

The plugin is now installed.

There are two configuration settings which can be used to override the folder link tooltips. These will be most useful for DokuWiki installations using a language not included with the plugin.

reveal — the title tooltip to be used by folding links when the folded content is hidden. If left empty the localised string will be used.

hide — the title tooltip to be used by folding links when the folded content is showing. If left empty the localised string will be used.

unfold_default — if this option is activated, then all sections will be unfolded per default.

show_fold_unfold_all_button — if this option is activated, then a button will be displayed in the toolbar. If it is clicked, the button folds or unfolds all sections at once.

The look of the folded sections can be customized by adding CSS code to userstyle.css. The following examples show the CSS selectors to be used to modify the style of the folded plugin:

Adding this CSS code to userstyle.css would give the clickable section a 2 pixel broad black border:

.folder {
    border: 2px solid black;
}
 
.folder.open {
    border: 2px solid black;
}

The selector .folder can be used to control the style of the folded state and the selector .folder.open for controlling the unfolded state.

Adding this CSS code to userstyle.css would give the unfolded section a 2 pixel broad black border:

div.folded {
    border: 2px solid black;
}
 
span.folded {
    border: 2px solid black;
}

The selector div.folded can be used to control the style of a block section and the selector span.folded for controlling the inline section.

Please feel free to add the strings for your own language here and I will add them to the next release of the plugin. If your language isn't included at present, you can override the strings that are shown using the plugin's configuration settings as described above.

There are also two strings used in the admin/configuration page.

With the help of the Wrap plugin you can create nested folds:

++++ Outer Fold |

The trick is to wrap the inner fold:

<WRAP>

++++ Inner Fold |

This is the content of the inner fold.

++++

</WRAP>

++++

Another method to achieve nesting is the Include plugin.

• support inline LaTex/MathJax and simple syntax like _… for subscripts, etc.
• allow usage of ++++ in the sidebar
• I'd also like to request nesting/nested folds. We use dokuwiki for our workplace, its great. Nested folds would be fantastic. Alex C 31/7/2013
• allow title formatting — Fred 2007-06-20 15:54
• Nesting folding sections… can be use for tree display and maybe other stuff —- Stephane Chamberland 2006-01-09
• When displaying search results, folded text needs to be displayed if it contains a search hit — Henry Olders 2006-04-08
• Make HTML id easier to understand. (for example I can put a link here based on the name, but the folded plugin ids are #folded_n - and if I link to that the folded section is not unfolded. This would make it much easier to do things for FAQs & such, like we are using. See?
• Have an “unfold all” option on the page, to allow browser text searches for pages like this.
  • Have “fold all” option as well

Would it be possible to use an image instead of text? the idea is to have a small image “help.png” to open a local explanation in a box. Thank you. Michel 2011-12-30
