Q: When I open my site in Internet Explorer 6.0 the main drop menu code shows up nicely but the drop-down sub-menus are separated. The drop menu code work very nicely in a Firefox browser but not in IE.
A: There are some problems also with your css.The problem is that the drop menu code 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:relative"). 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="position:relative;"
to the
<DIV id="right">
So, you'll have:
<DIV id=right style="POSITION: relative;">
Check that.
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: Thanks for your reply, I have another question as follow, I find the tree menu just expand one tree item, if I have expanded one tree when I click it, whether I click another tree to expand it's item and the before expanded tree are maintain expanded, I don't want to close it?
A: Use the following parameters:
var tcloseExpanded = 0; - Enables the mode when 1 item only can be expanded.
0 - disabled, 1 - enabled.
var tcloseExpandedXP = 0; - Enables the mode when 1 submenu only can be expanded (XP-style).
0 - disabled, 1 - enabled.
You can also try to set the following parameter:
var texpandItemClick = 1; - 0 - expand items on a [+]-button click only;
1 - expand items on a mouse click.
