Q: I got the menu to display across frames, but it displays differently in Firefox & Mozillavs. Internet Explorer. Is that to be expected?
In The Mozilla-based browsers, the submenu butts right upunder the main menu – which is how I want it. In IE, it is about 10 pixels below.
Also, I can’t get the submenus to drop down directly under the main menus – they are offset by about 100 pixels to the right.
A: The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, sosubmenus drop down with an offset.
You should create the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine awidth of the 1st column in the second row.
Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: Thanks for your reply, I have another question as follow, I find the tree menu just expand one tree item, if I have expanded one tree when I click it, whether I click another tree to expand it's item and the before expanded tree are maintain expanded, I don't want to close it?
A: Use the following parameters:
var tcloseExpanded = 0; - Enables the mode when 1 item only can be expanded.
0 - disabled, 1 - enabled.
var tcloseExpandedXP = 0; - Enables the mode when 1 submenu only can be expanded (XP-style).
0 - disabled, 1 - enabled.
You can also try to set the following parameter:
var texpandItemClick = 1; - 0 - expand items on a [+]-button click only;
1 - expand items on a mouse click.

Q: The cascading javascript menu does not spans frames or windows like Applets. Is that correct?
I was not able to make the sample to do it.
A: The DHTML Menu and Java Menu are built on different technologies.Java menus can create submenus that cover frames as a standard Windowssubmenus. DHTML Menu can't do that, because it's controls is htmlobjects, they can't overlap Windows controls. So, cascading javascript menu hascross-frame ability that allows it to show submenus in differentframes. But it can support this mode for the same domain only -- ifyou loaded a page to a subframe from another domain, the submenuscan't be shown in it. It happens because all browsers don't allow todo that for security reasons. Just imagine if you'll able to create aframeset from 2 frames, 1st frame will be with a zero height-width,and you'll load your page into it. Then user will go to another domainand your "invisible" frame will change a content of other pages!
