Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Deluxe Tree such as in Deluxe Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Deluxe Tree works fast, but 10000 is a large value. Please, try atrial version of Deluxe Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Deluxe Tree into the <table> or <div>.
Q: I'm trying to position my menus inside absolutely positioned <DIV> tags. If the <DIV> tag has style="position:absolute; top:100px; left:50px;" in the actual tag, deluxe-menu seems to work correctly. If I have the "position:absolute; top:100px; left:50px;" in a <STYLE> tag or a linked stylesheet and applied using id or class selectors, then deluxe-menu does not work correctly: sub menus have a 100pixel offset in the y direction and a 50 pixel offset in the x direction. This is with no change to the .js data file (I have absolutePos=0;) Is this a known issue, and is it planned to be fixed?
A: See, the problem is that the script can't get css properties of the object if they are described in separate .css block (or file).
In other words, you can't get the value of "position" attribute of the object if the object doesn't have this property within inline style(style="position:absolute"). To get the value you should move .css style into style="" attribute.
Please, try to add your
css file -> inline css, for example:
For example, you should add style="position:absolute;"
to the
<DIV id=head>
So, you'll have:
<DIV id=head style="position:absolute;">
Now we have only such solution for this problem.
We'll try to fix this problem in the future versions.
Q: I now have a tree on the left and an embedded frame on the right. When a user clicks a node, the corresponding html page appears in the frame.
Is there a method I can use when a user clicks a node, the web page will jump to a certain location in the page (menu dhtml hhyperlink)? I'm envisioning using one long web page instead of 30 or 40 separate pages. But I would need the program to work with a hyperlink to know where to jump to.
A: See the structure of tmenuItems array:
var tmenuItems = [
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFilename],
You can set link and target menu dhtml parameters for each item individually,for example:
var tmenuItems = [
["Home","files/homepage.html","","","","Home","topframe","","",""],
["Contacts","files/contacts.html","","","","Contacts","bottomframe","","",""],
You can also send us the example, so we can understand your problem.
Q: I have a Deluxe Tree Menu working on a website. What I want is that the javascript dhtml tree remembers which item was open when there is a click on an item.
I found on your website that this is possible with: var tsaveState = 1;
But when I want to use this option I need to include dtree_ss.js in the html page. I can not find this file in the zip file I downloaded.
Can you help me with this file or tell me where I can find it?
A: See dtree_ss.js file was in the first versions of Deluxe Tree. We don't have such filenow. We haven't updated info on your website on the following page yet
http://deluxe-tree.com/parameters-info.html
You should use dtree.js file only.
