Q: I am trying to use Delux-menu for our project, I am not able to use dynamic features of drop down menu script. I will send the html file, where I am calling the java script.
I am getting the error dm_menu[mInd] has no properties.
A: You have one menu in your example, but you write:
function hide(vis) {
dm_ext_changeItemVisibility(1, 0, 2, vis);
That is mean that you want to hide item in the second drop down menu script.
You should write:
function hide(vis) {
dm_ext_changeItemVisibility(0, 0, 2, vis);
Q: How change the color of the link in the dhtml vertical menu if the link is already visited.
A: JavaScript Tree Menu has only two states normal and mouseover,
butyou can highlight menu items in two ways:
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: May I use this menu in Arabic mode I mean in right to left mode?
If yes please let me know how?
A: You're able to use any characters for JavaScript Tree Menu in the same way asyou use them for standard html page.
The only issue is that submenus can be shown in incorrect positionwhen you're using dir=rtl for your page.
var dmRTL = 0;
Set this parameter to 1 if you're using right-to-left direction of html page <HTML dir=rtl>.
Use also
var smViewType = 2;
for right-to-left languages.
Please, see example:
http://deluxe-menu.com/ways-showing-submenus-sample.html
This examples demonstrates how the menu can change a submenusdirection. Use var smViewType parameter to change a submenusdirection:
var smViewType = 0..3;
Values:
0 - from left to right;
1 - from left to right + upwards;
2 - from right to left;
3 - from right to left + upwards;
In JavaScript Tree Menu when you call data .js file you can try to specify the encoding:
<script src="data.js" charset="utf-8"></script>
Unfortunately, you can't use arabic characters in Deluxe Tuner application.You should manually correct your code.
Q: I’m trying to setup a simple DHTML MENU (TREE MENU). It works just fine. I just have an issue that I can’t solve.
The parameter “ var tmenuHeight = "0"; Your documentation says the following
-----------
Height of the menu in (px, % or other units).
If the value 0 - the menu sets its height automatically.
If the value is small - scrollbars appear.
In IE it looks fine but I cannot see the menu in Firefox. When I set the parameter to for example 100 then it shows up both in IE and Firefox. But I cannot set a value in pixels. I don’t know how big the menu is because it’s dynamically built. According to your doc I can specify the value in percentage but this doesn’t work. When I set the value to “100%” it doesn’t show up in Firefox again.
How can I solve this issue?
A: Try to set this parameter in the following way:
var tmenuHeight = "auto";
