Q: I downloaded the free trial version and so far it looks like we can do everything. I have a couple questions:
the designer wants it so that when any of the submenu choice are selected, the main main menu in java item should be highlighted when the submenu page is displayed (kind of a breadcrumb). So, is there any way to change the background image of one of the main menu items after the menu loads? I haven't tried running my main menu in java in a webpage yet so I'm not sure if you generate a separate CSS file or put all of the settings into a STYLE= attribute of each tag.
A: The main menu in java has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, forexample:
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<script type="text/javascript"> var pressedItem=3;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem. You can't get this ID after you reload your page. That is why you should write your own code on PHP.
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: 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:
http://deluxe-menu.com/rq-loading-bar-MySQL-support.html
This example is not for Deluxe Tree menu, but you can create your menu in the same way.
Q: I have read your http://deluxe-tree.com/whats-new-info.html.
And really I do not understand this phrase:
- Item ID format has changed. It depends on the parent ID = [parent ID]i[item index].
Examples: for the first level dtree _0i0, dtree_0i1..., for the second level dtree_0i1i0,dtree_0i1i1, dtree_0i1i2...
Where do I fill in?
Do I have to rename my cascading menu titles?
A: Actually you shouldn't change anything.
This info is for the customers who use these indexes (dtree_0i1i2) only.
