How Do I make Collapsible Menu SAVE STATE


Poster: RegGFX
Dated: Thursday February 23 2006 - 17:52:04 GMT

Ok... i love the Collapsible Menu located at http://www.milonic.com/treemenu/

But ONE BIG QUESTION OF THE DAY...
In my brief quick look and study of this menu I have people requestiong to make it SAVE STATE when it gets to the next html page.

8O What it does now is COLLAPSE when you go to the next page.
Is there some kind of way to make it NOT shut back, but stay open when you visit a page? I know you could do this if you use frameset... but that is not an option for what i've been asked to do.

Perhaps this could be accomplished by COOKIES?,Onload being called or something?

Please RSVP

Hi,

If you are using links to navigate the treemenu (I guess you are) you can probbly just tag the openmenusbyurl.js module to your HTML.

This needs to go just after your menu_data.js call like this:

Code: Select all

<script type="text/javascript" src="openmenusbyurl.js"></script>


The link for the module is: http://www.milonic.com/openmenusbyurl.js

Hope this helps,
Andy

Andy, I'm a little confused, I need the same lack of collaspe to happen when the page is directed to another. In the case of the collapsable tree menu, rather than inserting the call just after menu_data.js, did you mean collapse_data.js, or treemenu.js? At the moment, I have the openmenusbyurl.js call in between and it does not work. The actual menu is good, if a little slow to react to mouseover changes. Another odd thing that happens when configuring the setup of the font, color etc, is one has to quit/restart ones browser to view the changes made! However, a small price topay for the end result. :D
As a result of the posting after this one, I've tried the new version of treemenu.js and putting the call for openmenusbyurl.js AFTER treemenu.js. However, I still wait to witness it working. :(

Save State for Menu

Yes... I have the same concerns... I'm still having trouble initiating a save state for this type of menu. It would be an enhancement that would be greatly appreciated.

Any other ideas or suggestions? :?:

I've found some rather interesting code example where a save state is being accomplished... the only trouble is i'm unsuccessful in trying to blend it into the Milonic Code :oops:

If someone or anyone at Milonic could take a look and try something similar I'm sure a similar save state could be achieved using the sample code below:

Code: Select all

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Savestate example</title>
<!-- ***NOTE*** All Code Below is Presented for educational and example purposes so that we may somehow achieve a similar save state feature to the Milonic Collapsible Menu (WHICH IS A FANTASTIC MENU.. It just doesn't save its state on a page. -->
<style type="text/css">
#tablist{

list-style: none;
display: inline;
margin: 0;
}
#tablist li a{
padding: 3px 0.5em;
