Manual talk:Collapsible elements

Doesn't work?
This didn't work correctly in my Mediawiki 1.12.0 install. Looking at the source code of the page it created, initially hidden content is indeed hidden, but there is no "Show" link to reveal the content. Do you have any ideas? --Gadlen 19:13, 5 June 2008 (UTC)

I'm not seeing the "hide" or "show" links
I'm running 1.13.4. any thoughts, could it be firefox? --69.244.124.138 01:16, 17 March 2009 (UTC)

still doesn't work any thoughts this what is is displayed:
Edited both common.js and common.css This is the header cell, which is always shown This cell is not shown by default.

(no hide or show links)

This does work for me (IE6, Firefox 3 and MediaWiki 13.4)
I had to change the function below the rest stay as it is. --AndreasMueller 21:56, 26 May 2009 (UTC) function createCollapseButtons {   var tableIndex = 0; var NavigationBoxes = new Object; var Tables = getElementsByClassName(document, "table", "collapsible"); for ( var i = 0; i < Tables.length; i++ ) { /* only add button and increment count if there is a header row to work with */ var HeaderRow = Tables[i].getElementsByTagName( "tr" )[0]; if (!HeaderRow) continue; var Header = HeaderRow.getElementsByTagName( "th" )[0]; if (!Header) continue; NavigationBoxes[ tableIndex ] = Tables[i]; Tables[i].setAttribute( "id", "collapsibleTable" + tableIndex ); var Button    = document.createElement( "span" ); var ButtonLink = document.createElement( "a" ); var ButtonText = document.createTextNode( collapseCaption ); Button.className = "collapseButton"; //Styles are declared in Common.css ButtonLink.style.color = Header.style.color; ButtonLink.setAttribute( "id", "collapseButton" + tableIndex ); ButtonLink.setAttribute( "href", "javascript:collapseTable(" + tableIndex + ");" ); ButtonLink.appendChild( ButtonText ); Button.appendChild( document.createTextNode( "[" ) ); Button.appendChild( ButtonLink ); Button.appendChild( document.createTextNode( "]" ) ); Header.insertBefore( Button, Header.childNodes[0] ); tableIndex++; }   var Tables = getElementsByClassName(document, "table", "collapsed"); for ( var i = 0; i
 * So, I think the plugin will work if you add these lines again and fix the syntax errors above (or just remove everything from your MediaWiki:Common.js except this:

 * Helder, thank you a million times. That was the problem all right.  Thanks.  24.40.138.185 06:22, 30 June 2011 (UTC)

Indication of collapsed/expandable status

 *  Moved from Meta-Wiki 

Hi,

This might be the wrong place to ask, but we were wondering if their is an easy way to know which status of the class="mw-customtoggle-myDivision" is set in terms of being collapsed/expandable.

Using the standard solution indicates the status through the display of either [Collapsed] or [Expand], in our case we trigger the area which need to be collapsed with the display of an icon, and as soon the user switches from one status to the other one we wanted to indicated a change through a change in the icon displayed. So in case the class contains "mw-collapsible mw-collapsed" display one type of icon, and in case of the class just being "mw-collapsible" display another icon. --MWJames 18:13, 6 July 2011 (UTC)
 * Hi MWJames,
 * If you can provide a link to where this happends on a live-wiki I may be able to give a more fine-tuned detail. I'll show you how I would do it though. I'm assuming your toggle-icon is inside :

Wikitext:

CSS:
 * A demo of this can be found at testwiki:User:Krinkle/CollapsingTestpageMw
 * Note that the  is not required, it's just to make sure it won't apply to other collapsible constructions on the same page. Use whatever identifier you like Krinkle 21:14, 6 July 2011 (UTC)

makeCollapsible "in core"
Does "in core as of MediaWiki 1.18 or higher" mean that it will be enabled by default on all wikis, loaded and activated on every page? If so, will there be any way to disable it? --Yair rand 08:54, 14 July 2011 (UTC)
 * There is nothing to disable as all the scripts mentioned on this page are only triggered if there are elements on the page marked as "mw-collapsible". If your wiki doesn't want or have collapsible elements, this script will not be triggered and nothing will change when upgrading to 1.18. Krinkle 04:21, 4 August 2011 (UTC)
 * Really? It won't even load the scripts or take up time running any JS if there aren't any mw-collapsible elements in the wikitext? --Yair rand 05:14, 4 August 2011 (UTC)

Use new 1.18 collapsible in 1.17
You can use the new 1.18 collapsible code in a 1.17 install. Just paste the contents of jquery-makeCollapsible.js into your MediaWiki:Common.js

Download head version from MediaWiki

Then at the bottom of MediaWiki:Common.js, add:

mw.messages.set({"collapsible-collapse":"Collapse","collapsible-expand":"Expand"}); $(document).ready(function{ $('.mw-collapsible').makeCollapsible; });

And add the contents of jquery.makeCollapsible.css into your MediaWiki:Common.css

Download head version from MediaWiki

If there is a tidier way of doing this, please let me know. --Thenickdude 11:33, 13 September 2011 (UTC)

Autocollapse
Has a version of autocollapse been implemented in core in 1.18? --★ → A  ir  on Ĉ  14:09, 7 October 2011 (UTC)

Common.js script (Before 1.18) don't works
Hey there!

I have some Wikis running on an Debian Linux 6.0 (Squeeze) Webserver. MediaWiki 1.17.0 (Version 95135) PHP 5.3.3-7+squeeze3 (apache2handler) MySQL 5.1.49-3

and i have the Problem, that this Collapse Hide & Show didnt works. I try it on two local Servers installed in Virtual Box and i have there the same problem. Could it be, that Debian Squeeze is the problem? Ive tryd all things, that i found here. But without a happy ending... Yukii 12:27, 10 October 2011 (UTC)

mw-collapsible will not work (1.18)
I've copied and pasted the examples and none of them work no matter what I do - upgraded my wiki, completely reinstalled the wiki, no dice. Leangle 8:54 PM, Dec 29 2011

Customizing Collapse/Expand location
Using 1.18, how would I customize the mw-collapsible mw-collapsed CSS so that the 'Expand' or 'Collapse' buttons appear on the left?

I'm thinking of something like what the mobile site does for certain sections - rather than having the 'expand' button float out of site off to the right, i'd prefer it to be on the left. It doesn't necessarily need to use a button, but that would be interesting as well.

66.3.56.92 23:21, 1 March 2012 (UTC)

Update:

Solved it, more or less

.tablecollapse span.mw-collapsible-toggle{ float:right; } .collapse span.mw-collapsible-toggle { float: left; }

By setting those classes, I can make sure that for tables, the toggle still appears where it should, and for other areas, the toggle appears floating left.

not sure how to swap out images, but at this point, thats no big deal. Hope this helps someone.

Only Works for Anons
When i log into my wiki the expand/collapse links disappear and all content within them defaults to expanded. Any idea on how to fix this? I'm thinking it's not loading the java after login but don't know what to change to fix it.

Thanks!

Extensions that disrupts collapsible elements.
I notice that with mediwiki 1.17 I didn't have any collapsible elements, even doing all the things to be done. I upgrade to mediawiki 1.18, and didn't work.

So I notice that, when I disable the Page Object Model Extension It worked.

Check it.

1.19.1 Nested Collapsible elements
In 1.19.1, using the builtin JQuery mw-collapsible and mw-collapsed classes works as expected, except if you have nested elements and "Expand" a collapsed element, it will also expand all nested elements. Ideally this could either be toggled via a setting or by default not expand all child collapsible elements.

19.2 - Collapsible Elements Load Open
I was previously using the now obsolete ToggleDisplay extension which worked nicely but now after upgrading to 1.19.2 I have started trying to use the built in Collapsible elements feature. It seems fine but when the page loads, all toggle areas load as open and only close once the page is completely loaded. This creates a kind of unwanted stutter in the visual loading of the page. Can this be fixed or is there a way to use Collapsible elements so it doesn't do this? The reason I mention the extension above is that it doesn't do this. The page loads with elements already closed and it looks great. Would love to have that effect again.

Loading issue
Is it possible to keep all the content collapsed while the rest of the page loads? I have a problem that, on pages with many images and other content, the information that I have initially collapsed is visible until the entire page loads in the browser.

Broken in Old Custom Skins
This functionality has been completely destroyed in pre 1.17 skins. It is impossible to implement any of the fixes suggested as the skins do not conform to the new framework, and the files used in the old framework no longer exist. Can anyone suggest a fix to re-implement this behaviour in pre 1.17 skins?

Custom Toggle with arrow indicator and header
This code makes a nice Toggle element with an Arror indicator image. The image can be anything really but an arrow is the most logical choice. I have not tested backwards compatibility on this for MediaWiki versions < V1.21. Credit goes to Krinkle as this was adapted from his examples.
