Recent Questions Javascript Tree Representation
Q: I recently purchased your Deluxe-Tabs product and I am trying to create tabs that occupy 100% width with each tab being equal width.
Right now when I specify 100% menu width all of the tabs are difference sizes (widths).
How do I control the individual tab width?
A: You should use Individual Item styles to achieve this effect.
See the attached example.
You should set:
var bmenuWidth="100%";
I have 5 items in my example, so I've created Individual Style
var bstyles = [
["bitemWidth=20%"],
];
And assign it for all items:
["Item 1 aaaaa ssssss","", "", "", "", "", "0", "", "", ],
["Item 2 ffff jjjjjjjjjj","", "", "", "", "", "0", "", "", ],
["Item 3 text text","", "", "", "", "", "0", "", "", ],
["Item 4 text text","", "", "", "", "", "0", "", "", ],
["Item 5 text text","", "", "", "", "", "0", "", "", ],
But notice that items width cannot be smaller than the width of its'text. So it is possible that you'll have different size of some itemsif your window have a small size.
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.
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 Javascript/DHTML Tree into the <table> or <div>.
Q: I am using JavaScript JavaScript Tree Menu v3.1 and have some problem with the doctype declaration. If I use the declaration:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
the menuBackImage and itemBackImage images do not display properly. Check with and without doctype declaration. Is there a known fix for this?
A: You should specify units in "px" for the javascript menu object.
var itemPadding="15px 10px 0px 20px";
var menuStyles = [
["smColumns=2","itemPadding=25px 10px 10px 10px"],
["itemPadding=25px 10px 10px 20px"],
["menuBackImage=img/nahbp_1.gif","itemPadding=25px 10px 10px 20px"],
];
Q: We are in the stage of design, we have a requirement to have the right click drop down menu fly out from right to left.
A: The following parameter controls the ways of showing submenus:
From left to right:

From left to right + upwards:
var subMenuAlign="left";
var subMenuVAlign="bottom";
From right to left:
var subMenuAlign="right";
var subMenuVAlign="top";
From right to left + upwards:
var subMenuAlign="right";
