Recent Questions Script Tree Menu Howto
Q: We recently bought your product.
We are developing in ASP.NET (VB) and we have a problem making you deluxe menu dynamic to suit our needs. We are using the JavaScript Tree Menu.
The problem is each time a page with dhtml nav loads, we want to be able to generate the menuItems variable to reflect the options the individual user has, so it can't be hard coded into data.js it MUST be provided by an aspx file and attached somehow. I can't work out how to attach the variable (even a static one) as a separate file, so if you can do it with a static one, we can extend it to a dynamic one later.
For example the JS in the data.js file we want the MenuItem dimension you be loaded in a seperate file, some kind of include.
var menuItems = [
["Home","index.aspx", "", "", "", "_self", "", "", "", "", "", ],
["About","about.aspx", "", "", "", "_self", "", "", "", "", "", ],
["Contact","contact.aspx", "", "", "", "_self", "", "", "", "", "", ],

Hope this makes sense.
A: You can move
var menuItems = [
...
];
dm_init();
dhtml nav code from your data file to your page (template) directly:
<script>
var menuItems = [
...
];
dm_init();
</script>
Q: Is there maybe a way that I can set up the menu so that it does not load at all until someone clicks on, say, a link, such as 'Products' and clicking on that link would then load the java menu buttons onto the page in the desired position?
A: Yes, you can do it.
Delete dm_init(); function from data file and use OnClick event foryour 'Products' link.
<a href="products.html" OnClick="dm_init();">Products</a>
Q: Does you tree menu javascript support right-to-left layout?
That is to say it opens the branches/submenus from the right to left.
A: Yes it is possible to create a menu for right-to-left languages with Javascript/DHTML Tree in the same way as in standard htmlcode.
Please, set <HTML dir="rtl">. You should set the following parameters:
var titemAlign="right";
var ticonAlign="right";
var texpandBtnAlign="right";
JavaScript Tree Menu support right-to-left languages.
In JavaScript Tree Menu you can set the following parameter:
var dmRTL = 1;
Set this parameter to 1 if you're using right-to-left direction of html page <HTML dir=rtl>.
Q: I am using cross frame menu dropdown. I have three frames: Top, Left and main (middle).
I am using the script and data from your sample file; it works fine. Only problem is submenu is offset to the right. It does not show up exactly down below the top menu.
What could be the problem?
A: JavaScript Tree Menu doesn't work correctly (incorrect submenu position) if youhave complex frame structure.
The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, so submenus drop down with an offset.
You should create, for example, the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine a width of the 1st column in the second row.
You should write init function in the following way in that case:
dm_initFrame("mainframe",1,3,0);
