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: Now on IE for Windows, the menus disappear as I roll over them, though not always.
I'd say 90% of the time they fade away as my cursor crosses them.
10% they stay and I can get a good click.
On Safari, they work great.
A: See menu parameters they contain:
var smShowPause=0;
var smHidePause=0;
You should set, for example:
var smShowPause=200;
var smHidePause=1000;
Try that.
Q: I need to use an iframe within the popup window.
Is there any way I can close the dhtml window from the page loaded within the iframe?
A: You can close the popup using the following function:
document.getElementById('win').hide();
Unfortunately it won't work if you use iframe as window content.
You open another page in the popup (in Iframe) so you cannot access
document.getElementById('win').hide();
element which is situated on the first page.
When you use text or object_id as window content the content of the popup will be situated
on the same page so you can access document.getElementById('win') element and hide it.
There is a workaround.
Use text as content type and add the following code inside popup:
<a onclick="document.getElementById('win').hide();">...</a><iframe></iframe>
Your link will work in that case.
Q: My Submenu is faded too quickly if I pull the mouse away from the java drop down menu.
A: You can try to use Deluxe Menu - this is a newer version of DHTMLMenu. You can use the following parameters there:
var smShowPause=200;
var smHidePause=5000;
