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: How can I add a submenu to the parent javascript menu horizontal?
A: You should add '|' symbols before item's text.
["Samples","", "", "", "", "", "", "", "", "", "", ],
["|Sample 1","testlink.htm", "", "", "", "", "", "", "", "", "", ],
["|Sample 2","testlink.htm", "", "", "", "", "", "", "", "", "", ],
["||Sample 2","testlink.htm", "", "", "", "", "", "", "", "", "", ],
Actually you can create your menu easily in Deluxe Tuner GUI tool.
Q: Under Opera everything works fine but under IE the submenu’s are way down the page and go off the bottom of the screen.
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="PADDING-BOTTOM: 10px;"). To get the value you should move .css style into style="" attribute.
Please, try to add your
css file -> inline css, for example:
You should add style="PADDING-BOTTOM: 10px;"
to the
<DIV class=department-menu>
So, you'll have:
<DIV class=department-menu style="POSITION: absolute;PADDING-BOTTOM: 10px;">
Q: Is there any way to have the browser reset the horizontal tree view to allcollapsed each time the browser is reopened?
A: You should set the following parameter in that case:
var tsaveState=0;
