Q: Can I use my own images as the tabs in a div tab menu?
A: The Drop down menu items have the following structure:
var menuItems = [
[text, link, iconNormal, iconOver, tip, target, itemStyleInd, submenuStyleInd, jsFilename],
[text, link, iconNormal, iconOver, tip, target, itemStyleInd, submenuStyleInd, jsFilename],
...
];
Where iconNormal, iconOver - Icons of an item: icon in normal state, icon in mouseover state.
So you can set your menu items in a such way:
var menuItems = [
["","testlink.htm", "icon1.gif", "icon1o.gif"],
["","", "icon2.gif", "icon2o.gif"],
["|","testlink.htm", "icon3.gif", "icon3o.gif"],
["|","testlink.htm", "icon4.gif", "icon4o.gif"],
["|","testlink.htm", "icon5.gif", "icon5o.gif"],
["","testlink.htm", "icon1.gif", "icon1o.gif"],
];
Q: Is there a way to change the height of the main buttons in Dhtml Menu. When I use the GUI tool there is nowhere to change the main button height. And when I tried to change it in the script file, it did me no good. I want all of the main buttons to be the same size.
A: You can use standard <img> object to set menu height, for example:
var menuItems = [
[" <img src='blank.gif' width=1 height=50>text"],
];
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: Can you provide an example of how to dynamically change the menu items at runtime for the dropdown menus?
(asp is fine, but if it needs to javascript that is also ok)
A: 1) You can use API functions to affect items dynamically:
http://deluxe-menu.com/functions-info.html
2)Generate your menu items dynamically from database.
Unfortunately we don't have working example with ASP.
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.:
<!-- JavaScript Tree Menu -->
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<!-- (c) 2008, http://deluxe-menu.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var menuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
</script>
The example of the menu working with PHP/MYSQL you can find here:
