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)

I composed to the two above messages... any thoughts on how to resolve this and would like to use collapsible tables
Is this code for 13.3 + ? --Mappc 00:00, 5 April 2009 (UTC)

I'm still interested in getting some resolution....any thoughts --Mappc 22:54, 6 April 2009 (UTC)

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 < Tables.length; i++ ) { collapseTable( i ); }   var Tables = getElementsByClassName(document, "table", "autocollapse"); for ( var i = 0; i < Tables.length; i++ ) { if ( i >= autoCollapse ) { collapseTable( i ); }    }	}

Worked A-OK
No editing needed over here. Using MediaWiki 1.15.1 with no other custom JS. 74.65.88.219 01:55, 7 October 2009 (UTC)


 * Worked for me too on 1.15.1. At first it was very frustrating, I couldn't get it to work, but all I needed to do was the Shift-Refresh thing in my browser. =D --J.nesta 18:36, 5 November 2009 (UTC)

hide/show placement not working
I updgraded to 1.15.1. Now my hide/show buttons are always on the left even though I have the Common.css file with float right. See at http://sunshinereview.org/index.php/User:Ljarratt

1.16 functionality
Beta 3. This function works flawlessly for me.
 * Funny, not doing a damn thing for me (as describe, prior to 1.7 in the main article)
 * MediaWiki 	1.16.2
 * PHP 	5.2.11 (apache2handler)
 * MySQL 	5.0.77

1.15.3 Not Working - Using skin Cavendish
can anyone help with making this functional? http://emajenanything.com/mainwiki/wiki/index.php?title=Test THANKS

What?
How come I don't have neither common.js nor common.css in my wiki? how do I make this effect? :( --201.255.119.39 07:22, 19 July 2010 (UTC)
 * You can create them using your search box and searching for

MediaWiki:Common.css MediaWiki:Common.js

show/hide: jumping to top
A click on my show/hide button causes the page to jump to the top. Any ideas? Gohnarch 20:30, 27 September 2010 (UTC)


 * I have same problem on two different installs of 1.15 (Ubuntu and CentOS) - tried code from "This does work for me ..." above and that seems to be OK for now ... WBN 82.41.58.191 23:49, 13 October 2010 (UTC)


 * That's as a result of these two lines

ButtonLink.setAttribute( 'href', '#' ); addHandler( ButtonLink, 'click', new Function( 'evt', 'collapseTable(' + tableIndex + ' ); return killEvt( evt );' ) );


 * If you look at the current mw MediaWiki:Common.js, it reads

ButtonLink.setAttribute( 'href', "javascript:collapseTable(" + tableIndex + ");" );


 * (see Fragment identifier). I will update the page to show this change if that is all right with everybody. --JCrue 18:24, 30 November 2010 (UTC)

Still not working
Hi, I'm trying to install this on 1.15, and the "hide/show" tags aren't appearing. I've edited the common.js and common.css, as above and as shown on the article page, purged webcaches, etc, etc, and still no go. Any ideas for how to troubleshoot this? - very frustrating!

1.17 example not working on diffs
Hi!

I noticed that the new examples doesn't works when the page is seen in a diff like this. I think it should work even in this case (not only when viewing the page directly). Helder 16:03, 23 February 2011 (UTC)
 * During development it worked fine in preview, diff and oldid view. Will look into it. Krinkle 11:00, 24 February 2011 (UTC)
 * It does work in the latest development version, as for example ran on TranslateWiki, here. Hm.. Krinkle 11:32, 24 February 2011 (UTC)
 * Seems the cause isn't in the script after all. The problem is the FlaggedRevisions-extension which loads the page-contents afterwards via JavaScript causing any onload handlers to fail miserably since there isn't a page at that time (TOC-toggle, mw-collapsible, mw.util.$content) See also 26175 and  27513. I can't fix this untill FlaggedRevs has some kind of hook or is fixed otherwise. Any javascript handlers will fail (potentially $.fn.placeholder and $.fn.checkboxShiftClick as well) Krinkle

Cannot get Collapse to work in 1.17
I have tried to different 1.17 installs and I cannot get collapse to work at all. I am following the examples exactly:


 * This is text is collapsible.
 * This is text is collapsible.

Just shows the text. There is no option to collapse. The other examples give the same results. The ability to collapse is completely missing, even though the directions say "After 1.17... Basically all you do is add the class "mw-collapsible" to an element." What am I missing?


 * Site #1: http://wiki.cyanogenmod.com/wiki/User:Pconwell/sandbox2
 * Site #2: http://w.gu1dry.com/User:Pconwell/Sandbox2
 * I can't get this to work over at http://everquest.wikkii.net either. I also couldn't get the old style of collapsible tables using common.css and common.js to work either.  I'm going nuts trying to figure out what I have done wrong.   24.40.138.185 21:52, 24 June 2011 (UTC)

On ResourceLoader/Default_modules it is said that this feature is currently available on trunk, since 78914, but there is no mention of MW 1.17. So, I think this page is outdated.

Anyway, on this page it is explained how to install the plugin on MW 1.17 (as was made here on MediaWiki.org). Helder 12:43, 28 June 2011 (UTC)
