Q: I am facing problem with deluxe tab. When a first level jscript tab is selected, sub tab of that tab should be in selected mode.
I need to change text color of "New contact" (sub tab) in selected mode to black.
A: Unfortunately Deluxe Tabs doesn't have such a feature now.
You use main tabs to show sub-tabs and click on sub-tabs to show their content or openlinks.
On the initial page load you can set the selected item and submenu item using thefollowing parameters:
var bselectedItem=1;
var bselectedSmItem=2;Q: I need to execute some javascript first when someone clicks on the tab in the floating tabs.
A: You should paste "javascript:some_function()" into item's link field, for example:
["tab text","javascript: window.open('test.html', 'frameName')", ...],
or
["tab text","javascript: getURLForFrame()", ...],
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: We are wanting to make this collapsible menu Dynamic by reading from a Microsoft SQL Data base.What is the approach in accomplishing this?
A: You may generate a menu from a database or XML using any server-side script, e.g., PHP, ASP, VB, etc.
However, these scripts don't work inside of Javascript .js files, so, you should move parameters of a menu from a .js file into an html-page, e.g.:
<noscript><a href="http://deluxe-tree.com">Javascript Tree Menu by Deluxe-Tree.com</a></noscript>
<script type="text/javascript" src="menudir/dtree.js"></script>
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var tmenuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
The example of the menu working with PHP/MYSQL you can find here:

This example is not for Javascript/DHTML Tree menu, but you can create your menu in the same way.
