Q: Will all your navigation bar examples work cross-frame?
A: See how should you create cross frame menu:
1. To initialize the cross frame menu call dm_initFrame()
function instead of standard dm_init() function within data.js file:
dm_initFrame(framesetID, mainFrameInd, subFrameInd, orientation);
framesetID - id attribute of the frameset;
mainFrameInd - index of the main frame (where the top-menu is placed), >=0;
subFrameInd - index of the subframe (where the submenus will be shown), >=0;
orientation - frame orientaion: 0 - top-to-bottom, 1 - left-to-right; 2 - bottom-to-top; 3 - right-to-left.
So you should create your menu in Deluxe Tuner, save it.
Create html file with your frame set.
Set ID for the first frameset:
<FRAMESET id=frmSet rows=220,*>
<FRAME id=frame1 src="JavaScript Tree Menu Samples_files/cross-frame-horizontal-1.htm"> //menu frame
<FRAME id=frame2 name=frame2 src="JavaScript Tree Menu Samples_files/testlink.htm"> //content frame
</FRAMESET>
Then you should open your data file in any text editor and change
dm_init(); for example to dm_initFrame("frmSet", 0, 1, 0);

Q: How would I use the submenu feature to display itself only if a person is logged in. such as if a person logged in then the member area would expand, else it would always stay closed with only the login username section showing?
A: Unfortunately it is not possible. You can only add items depending onthe logged user.
You should use API functions:
see more info:

For example, you can use:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
function dtreet_ext_deleteItem (menuInd, itemID)
function dtreet_ext_showItem (itemID, visibility)
function dtreet_ext_expandItem (itemID, expand)
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 Javascript/DHTML Tree such as in JavaScript Tree 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.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML 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 Javascript/DHTML Tree into the <table> or <div>.
