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 Javascript/DHTML Tree such as in JavaScript Tree 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.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML Tree.
