Expand/collapse all regions

I have 5 show/hide regions on a page. is it possible to Expand/collapse all regions by clicking a "Show/Hide All" link or a button. any ideas are appreciated.
thanks,
Surya

Hi Surya
Create a new HTML region at the top of your page, using No Template and use this as the Source:
<script type="text/javascript">
function showHideAll(displaystyle)
var hideIMG = "/i/htmldb/builder/rollup_plus_dgray.gif";
var showIMG = "/i/htmldb/builder/rollup_minus_dgray.gif";
var k;
var r = document.getElementsByTagName("DIV");
if (r)
   for (k = 0; k < r.length; k++)
     if (r[k].className == 't12Hide')
       r[k].style.display = displaystyle;
var i = document.getElementsByTagName("IMG");
if ( i )
for (k = 0; k < i.length; k++)
    if (i[k].id.substr(0, 5) == 'shIMG')
      i[k].src = (displaystyle == 'block') ? showIMG : hideIMG;
</script>
<a href="javascript:showHideAll('block');">Show All</a>
<a href="javascript:showHideAll('none');">Hide All</a>The image names and className (t12Hide) are based on my test page - change these as appropriate for your own page (you may need to do a View Source on the page to check these values).

Expand/Collapse All Version Sets

PSE 10, Is there a simple way to open all the Version Sets with one set of keystrokes, and having them stay open. I have a lot of version sets built up over time, and I would prefer not having to open each one individually. When I tried doing that on a small batch, as soon as I changed to a different batch of pics, all of the Sets I had opened, promptly closed. The View > Expand/Collapse All Stacks does not work on the Version Sets.

Expand/Collapse all the Bookmarks in a PDF file

Hi,
This is my first message on the board :-)
I work with very large PDF files (i.e 2000 pages, 700 bookmarks on 5 or 6 levels!) and I'm looking for a script (Acrobat 9 Pro) allowing to expand/collapse all the bookmarks in a PDF file.
Thanks in advance for your valuable help,
Cheers
Antonella

The Acrobat Javascript Scripting reference (http://partners.adobe.com/public/developer/en/acrobat/sdk/AcroJS.pdf) describes how to use scripting to access bookmarks and how to open and close them, which is what you're looking for.
I suggest you read the reference and make a function that will do the job for you.
That's the way I would do it.
I don't think you can access the keyboard shortcuts "/" and "Shift + *" via scripting.

Decision Report: Toggling Expand / Collapse All (v10.2)

Hi everyone,
We're wondering if anyone can share an approach for enabling users to "expand/collapse all" (all nodes) in a decision report dynamically - i.e. using a button or toggle, rather than a global configuration or preference setting. For example, we would like to initially display a collapsed report (to show the high-level conclusions), and then enable the client to fully expand the report for printing.
Importantly, we would like to be able to do this in version *10.2*.
Thanks,
- Patrick

Granting my JavaScript is a bit rusty, I'm wondering if anyone else has encountered the following challenge when changing the global configuration settings for decision report (expanded/collapsed):
Issue: The plus signs ( + ) at the nodes appear as minus signs ( - ), and vice versa. In other words, after our modifications, the user needs to click on a minus sign to expand a node.
Our approach was simply to do a CTRL-F and replace "expanded" with "collapsed", so it's not surprising that there were unintended side effects.

DHTML Tree Expand-Collapse ALL buttons

Hi
I am using at DHTML Tree (in APEX 3.0.1) as a menu. I am wondering if it is possible to add buttons (or link) to the region which a user can click to expand all or collapse all nodes in the tree.
I don not want the tree to be expanded or collapsed all the time (as when using the Tree List template)
Thanks

Anyone?

DTreeTable Expand/Collapse All

I was wondering if anyone had any experience with the DTreeTable plugin found here: http://apex-plugin.com/oracle-apex-plugins/region-plugin/dtreetable_68.html
If so, has anyone implemented an expand all or collapse all button with it?
An example of the onclick for each node is dttToggleNode('2597807651112537', 1) - I could loop through these and click them all but is there a nicer way?
Thanks.
EDIT: Here is the javascript it is calling. I'm thinking possibly loop through the whole page and do a variation of the two expand and collapse functions?
var el = $('#dtt_' + regionId + '_table tbody tr span.dtt_icon')[rownum - 1];
                if ($(el).hasClass('dtt_collapsed_span')) {
                               // call expand function
                               dttExpand(regionId, rownum);
                } else {
                               // call collapse function
                               dttCollapse(regionId, rownum);
function dttExpand(regionId, rownum) {
// get related table row
var el = $('#dtt_' + regionId + '_table tbody tr')[rownum - 1];
// store current level
var level = Number($(el).attr('dtt_level'));
// change icon
$(el).find('span.dtt_icon').removeClass('dtt_collapsed_span');
$(el).find('span.dtt_icon').addClass('dtt_expanded_span');
while ($($(el).next()).attr('dtt_level') != null) {
     var el = $(el).next();
     if ($(el).attr('dtt_level') == (level + 1)) {
      // change display
el.removeClass('dtt_collapsed_tr');
el.addClass('dtt_expanded_tr');
} else if ($(el).attr('dtt_level') == level) {
break;
function dttCollapse(regionId, rownum) {
// get related table row
var el = $('#dtt_' + regionId + '_table tbody tr')[rownum - 1];

Expand/Collapse all in OneNote 2013?

Once I've created a hierarchy in OneNote, is there any way I can collapse all or expand all in a single click, or am I destined to have to click more than 100 [+] when I want to see everything? Thanks.

Hi,
Do you mean you want to expand all collapsed outlines by single click? If so, we can use Alt + Shift + 0 to expand all levels in OneNote. Some related keyboard shortcut key are listed below:
Show through Level 1.
    ALT+SHIFT+1
Expand to Level 2.
    ALT+SHIFT+2
Expand to Level 3.
    ALT+SHIFT+3
Expand to Level 4.
    ALT+SHIFT+4
Expand to Level 5.
    ALT+SHIFT+5
Expand to Level 6.
    ALT+SHIFT+6
Expand to Level 7.
    ALT+SHIFT+7
Expand to Level 8.
    ALT+SHIFT+8
Expand to Level 9.
    ALT+SHIFT+9
Expand all levels.
    ALT+SHIFT+0
Increase indent by one level.
    TAB
Decrease indent by one level.
    SHIFT+TAB
Expand a collapsed outline.
    ALT+SHIFT+PLUS SIGN
Collapse an expanded outline.
    ALT+SHIFT+MINUS SIGN
Hope this helps.

Javascript to Expand/Collapse all grouped list items(2010 method no longer working)

I have the below little piece of javascript that used to work in 2010(with plus.gif/minus.gif)
<html>
<head>
<script language="Javascript" type="text/Javascript">
function collapseGroups() {
$("img[src*='spcommon.png']:visible").parent().click();
function expandGroups() {
$("img[src*='spcommon.png']:visible").parent().click();
</script>
</head>
<body>
<input type="button" id="btnExpand" onclick="expandGroups()" value="Expand All">
<input type="button" id="btnExpand" onclick="collapseGroups()" value="Collapse All">
</body>
</html>
This however does not work and results in a lot of "clicks" occuring on the site, wherever the spcommon.png is present(which is a lot)
Has anyone hit this issue before?
Regards
Pieter
PS. Works on 2010 with plus/minus.gif.

Can I expand/collapse all of my email accounts in the folder pane?

Greetings,
Thank you in advance for your help.
I'm using T-bird v31.0
The inbox is configured to view/layout/folder pane and view/folders/unified.
I have multiple email accounts that appear in the folder pane.
I can expand/collapse inbox, drafts, sent, junk, trash, but not the email accounts.
Is it possible to expand/collapse the email accounts?
Thank you for you hard work and expertise.
norm

Do you have the removed account forwarded to your other account at the server?
If the account is not still in Thunderbird there is no way for it to check mail on that account. Even if it did it would not place the messages in a different Inbox.
Just to be sure when you go to Tools-Account Settings is the old account still in the list?
Use Tools on the menu bar and not the AppMenu button.
No menu bar? Press the alt key.

Expanding and Collapsing All Nodes in a TreeByNestingTableColumn

Hi Experts,
I'm using NWDS 7.0.18.
I have a table with TreeByNestingTableColumn (master column).
The child nodes are recursive nodes and are loaded at runtime with an action onLoadChildren when clicking the master column. My question is, when the hierarchy is in its initial state, only the root node is loaded into the table. But I want to add functionality for expanding all nodes in the tree. Is there a way to achieve this, I'm a little confused because the Hierarchy children havent been loaded yet.
Any suggestion will greatly help.
Regards,
Kunal.

Hi Kunal,
I got your problem.
To expand & collpase all the child nodes please modify the code as below.
Create two methods exapndAll & collapseAll and call these two methods in existing button actions.
as below.
public void expandAll( com.sap.tut.wd.treetable.wdp.IPrivateTreeTableView.ICatalogEntriesNode node )
    //@@begin expandAll()
     for (int i = 0; i < node.size(); i++) {
     node.getCatalogEntriesElementAt(i).setExpanded(true);
     if(node.getCatalogEntriesElementAt(i).getIsLeaf()==false)
          expandAll(node.getCatalogEntriesElementAt(i).nodeChildCatalogEntries());
    //@@end
public void collapseAll( com.sap.tut.wd.treetable.wdp.IPrivateTreeTableView.ICatalogEntriesNode node )
    //@@begin collapseAll()
     for (int i = 0; i < node.size(); i++) {
     node.getCatalogEntriesElementAt(i).setExpanded(false);
     if(node.getCatalogEntriesElementAt(i).getIsLeaf()==false)
          expandAll(node.getCatalogEntriesElementAt(i).nodeChildCatalogEntries());
    //@@end
public void onActionCollapseAll(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionCollapseAll(ServerEvent)
    collapseAll(wdContext.nodeCatalogEntries());
    //@@end
public void onActionExpandAll(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionExpandAll(ServerEvent)
    expandAll(wdContext.nodeCatalogEntries());
    //@@end
We are invoking the methods recursively to expand/collapse all the child nodes.
This works.

Charan

JTree with XML content expand/collapse problem

Hello all,
I'm having this very weird problem with a JTree I use to display the contents of an XML file. I use the DOM parser (and not JDOM since I want the application to run as an applet as well, and don't want to have any external libraries for the user to download) and have a custom TreeModel and TreeNode implementations to wrap the DOM nodes so that they are displayed by the JTree.
I have also added a popup menu in the tree, for the user to be able to expand/collapse all nodes under the selected one (i.e. a recursive method).
When expandAll is run, everything works fine and the children of the selected node are expanded (and their children and so on).
However, after the expansion when I run the collapseAll function, even though the selected node collapses, when I re-expand it (manually not by expandAll) all of it's children are still fully open! Even if I collapse sub-elements of the node manually and then collapse this node and re-expand it, it "forgets" the state of it's children and shows them fully expanded.
In other words once I use expandAll no matter what I do, the children of this node will be expanded (once I close it and re-open it).
Also after running expandAll the behaviour(!) of the expanded nodes change: i have tree.setToggleClickCount(1); but on the expanded nodes I need to double-click to collapse them.
I believe the problem is related to my implementations of TreeModel and TreeNode but after many-many hours of trying to figure out what's happening I'm desperate... Please help!

              //for (int i = node.childCount()-4;i>=0;i--){
                   collapseAll(tp.pathByAddingChild(model.getChild(node,i)));
              tree.collapsePath(tp);
    private void expandAll(TreePath tp){

Iam not facing this problem. To CollapseAll, I do a tree.getModel().reload() which causes all nodes to get collapsed and remain so even if I reopen them manually.
Hope this helps.
cheers,

Expand/collapse folders in CS4 ?

Searched the forum and through offline help and tried every icon in the panels but can't find this.
In DW CS4 how do you expand/collapse all folders in a site automatically ? Either in panel view or expanded full screen view ?
Or do you have to open/close all folders individually ?
Thanks, Tim R

Or do you have to open/close all folders individually ?
Yes.

ER: "Collapse All" for Application Navigator

Using 10.1.3 production release.
would it be possible to add a "collapse all" button (or context menu entry) to the application/system navigators to quickly collapse the tree.
It is very easy to get lost, particularly when working on a large project and 'collapse all' allows quick re-orientation for the user.

Chris,
reference is ER 5043256 - ABILITY TO EXPAND / COLLAPSE ALL NODES AS IN OTHER ORACLE PRODUCTS
In case you have access to MetaLink, you can track the updates to the enhancement request from there (I published it).
Regards,
Didier.
