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: I regret having a problem with my setup, and hope you may be able to put me on the right track. After making a few alterations to my menu, and previewing in FrontPage,
I get a window with an error message "dmObjectsCheck is undefined".
A: This error means that you didn't add some engine file for themenu you need.
Please, try to add all engine files into the folder with your dmenu.jsfile.
You can also send me a copy of your html page (including .js files)and I will check it.
Q: Is the menu floatable?
I try the setting "float" but no change
A: You can't see floatable or movable effect in Deluxe Tuner preview.
But when your install your menu into the .html page it'll work fine.
Notice, when you use floatable menu you can't use relative menu position.
So, if you use
var absolutePos = 0;
and to center the menu you use <p> or <div> with the center alignment your menu won't float.
To center your floatable menu you should set absolute coordinates.
Q: I activated option "state saving" but I think there's a problem;
when I open the website and click on an item of the menu, the pressed item becomes red
(up to now it's ok), but if I have topress F5 on the keyboard or press on the refresh button
to refresh the web page, the pressed item loses its color red.
I'd like the pressed item in the dhtml expand menu to maintain its color after the refresh command.
How can I solve this problem?
A: Tree Menu doesn't save a presseditem as it saves a tree state.
It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function apyt_ext_setPressedItem(menuInd, itemID)
<script type="text/javascript">
var i = 4 //index of the selected item
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
</script>
