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 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.Q: Tree menu doesn't display properly in Firefox or IE7. Could you give me advice on how to correct this problem? The menu creates black 'blinds' horizontally across the page. Since IE7 will be rolling out soon I need to get this corrected sometime in the next couple weeks.
A: Try to specify units in "px".
var tmenuWidth = "280px";
It's necessary to specify exact value for Mozilla browsers. It helps to position menus correctly.
Q: We have been evaluating your menu control.
But we are not able to use PNGFix javascript which is used for transparent PNG image in our down navigation bar. Your menu is transparent but it goes one layes behind. It should come on top of all with transparecy.
Your reply could help us make a buying decision.
A: Unfortunately it is really so. PNGFix javascript won't work.
We'll try to add feature to use transparent PNG images in the next version of Deluxe Menu.
