Return to Recent Questions


Q: Hi, I need to know if it is possible to create the following things in your tree vertical scrolling menu library.

1. I need to have a checkBox in each vertical scrolling menu item and through a JavaScript function be able to add the selected nodes into another tree.
2. I need to delete the nodes that has check=true
3. I need to place a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). The area should remain its original size when collapsed or expanded. 4. I need to populate the vertical scrolling menu using AJAX
5. I need to have several trees on the same page
6. How your tree vertical scrolling menu would behave with 10000 nodes??



A: 1, 2. Yes, you can create such features. But you should create your own server-side script (for example, php) that will do it. The vertical scrolling menu doesn't support such a features.
3. You can place DHTML Tree Menu into the <table> or <div>.
4. Unfortunately, you can't use the AJAX-like technology in the DHTML Tree now.
5. You can add as many menus on the one page as you want.
6. It is possible that the loading speed will decrease if the vertical scrolling 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.
I tried to create large vertical scrolling menu on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
