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: I need to include background images for my navigation, so I put them in the same folder where the "data.js" file can be found. I am using the deluxe tuner in order to call these files and it looks great in the preview. As soon as I save the file and load it in the browser, the background images are missing.
Your solution refers to creating absolute paths using
var pathPrefix_img = "http://domain.com/images/";
I have implemented this solution but I still think the problem persists.
A: Now you set pathPrefix parameter:
var pathPrefix_img = "http://www.domain/folder/menudir/dataAlumni.files/";
And you have such images paths, for example:
var arrowImageSub=["dataAlumni.files/submenuIconOff.gif","dataAlumni.files/submenuIconOn.gif"];
So you have such paths for arrows:
http://www.domain/folder/menudir/dataAlumni.files/dataAlumni.files/submenuIconOff.gif
It is not right.
You should write your paths so:
var arrowImageSub=["submenuIconOff.gif","submenuIconOn.gif"];
Please, correct it.
Q: We are unable to get sub-menus to appear on page load or rather simulate a "windows application style menu".
How can we in combination with the java menu api function dm_ext_setPressedItem get the associated sub-menu to display? This function simply sets the item to "pressed" rather than actually showing the sub-menu. Attempts at beginning an item's text value with "+" only works with Javascript/DHTML Tree.
Again, we are trying to use the menu not only as a navigator but also as a visual aid for the user to determine what page they are viewing. For example, when a user clicks on a menu item and that page loads, the menu should display the top-level item pressed, the sub-menu group, and the item pressed.
Furthermore, it would also be useful if we could then "unlock" the pressed items and navigate the menu under normal circumstances.
If there are no existing "quick" functions to accomplish this, could you please point out the function in dmenu.js or another engine file that initiates the display of sub-menus, we could then force the menu to select a top-level item in the onload event thus showing a top-level item pressed along with it's related sub-menu.
A: Unfortunately JavaScript Tree Menu doesn't have such a feature now. It is notpossible to set parent item highlighted, expanded submenu group andhighlighted submenu item.
You can do it using Javascript/DHTML Tree now only.
Q: I have been working with on a site and I am kind stack using the program. I want to use the tree option but not all “buttons” need to have subcategories. For example:
Category 1
Sub-menu 1-1
Sub-menu 1-2
Sub-menu 1-3
Category 2
Sub-menu 2-1
Sub-menu 2-2
Sub-menu 2-3
Category 3
Category 4
When someone click on the “Category 1” or “Category 2”, I want them to see the sub-menus. However, when some click on “Category 3” or “Category 4”, I would like to have it open the appropriate page. How do I do this? This will make a lot easier because not all buttons need to have sub-menus… I hope that makes sense and you can help me on getting this done.
A: You cannot use links for the top items in XP Style only.
var tXPStyle=1;
but you can write:
["<a href='http://deluxe-menu.com'>Item 45</a>","", "", "", "", "", "", "", "", ],
