Recent Questions Rails 3 Tree Menu
Q: Is it possible to insert a dhtml foldout menu item at the top of the submenu? For example, if a dhtml foldout menu is defined as:
var menuItems = [
["Search","","","","","","1","0"],
["|Residential","srch.php","","","","","0"],
["|VacantLand","srch.php?cri","","","","","0"],
["|Commercial/Industrial","srch.php","","","","","0"]];
How can I add a new item above “Residential?” I’ve tried the following with no luck — the forth argument does not seem to be used:
dm_ext_addItem(0, 1, ["New Sample", "testlink.htm", "", "", "Your Sample Tooltip", "middle", 0], 0)
A: To insert item in the specific position you should use thefollowing function:
function dm_ext_addItemPos (menuInd, submenuInd, iParams, Pos)
Q: How does one go about changing the parameter or the JavaScript so that a vertical menu selection stays 'on'? In other words, the vertical menu remains selected, perhaps in a background color that shows the user this menu choice is selected and the user is in the selected menu area.
A: To save your navigation path you should set the following parameter:
var saveNavigationPath = 1;
The menu keeps items highlighted during menu navigation.
0 - disabled, 1 - enabled (default).
You can highlight menu items by default in two ways:
1) Set the pressed item on each page idividually using the following parameter:
var pressedItem = -2;
The toggle mode. Sets an index of an item that will be highlighted by default.
-2 - the toggle mode is disabled;
-1 - the toggle mode is enabled, but no items highlighted by default;
0,1,2,3,... - index of highlighted item in a top-level menu.
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, for example:
<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=2;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
2) Set the pressed item/subitem using dm_ext_setPressedItem () function.

Q: I can't find an instance of your java pop menu that can lay over top of a flash object without making the flash object disappear like your demo.
Does yours or doesn't it do the same thing and if so, where is there an example?
A: JavaScript Tree Menu overlaps flash in all browsers.
You can find fix for Firefox here:

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);
