Q: I have a menu defined that displays and operates correctly in a page. However, if I place that same page in an iFrame the menu displays correctly BUT the texpanded parameter no longer works.
If I copy the contents of the iFrame and run it again in a new window, it all works fine again.
Is there something special I need to do in an iFrame?
A: Javascript/DHTML Tree Menu doesn't work with <IFrame> objects. It works with
Q: How I can write the changed dhtml pull down menu into a database?
A: Unfortunately, we don't have such example.
You may generate a menu from a database or XML using any server-side script, e.g., PHP, ASP, VB, etc.However, these scripts don't work inside of Javascript .js files, so, you should move parameters of a menu from a .js file into an html-page, e.g.:
<!-- Javascript/DHTML Tree -->
<noscript><a href="http://deluxe-tree.com">Javascript Tree Menu by Deluxe-Tree.com</a></noscript>
<script type="text/javascript" src="menudir/dtree.js"></script>
<!-- (c) 2006, http://deluxe-tree.com -->
<script type="text/javascript" language="JavaScript1.2">
// and describe parameters of a menu
var parameter1=value1;
var parameter2=value2;
etc.
var tmenuItems = [
// here you generate items using server-side scripts (php, asp, vb, etc.)
];
</script>
The example of the menu working with PHP/MYSQL you can find here:

This example is not for Javascript/DHTML Tree menu, but you can create your menu in the same way.
Q: I can’t highlight the selected menu item of the current page in the javascript flyout menu?
A: Please, check the following parameter
var pressedItem=-2;
This parameter 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-menu.
The menu has only two states normal and mouseover. We'll try to add the pressed state in the future.
You can set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page.
That is why you should write your own code on PHP.
You can also set the correct:
var pressedItem=1;
parameter on each html page.
Q: The problem that I'm having is when ever the menu has an external link clicked to load in the main frame, the main menu (blue one with icons) dropped down & the frame below is moved to the bottom ofthe menu, or in other terms the menu frame stretches to the size of the menu & moves the main frame down.
A: The menu will work correctly in the cross-frame mode if you load pages into the sub frame from the same domain.
If you load pages from another domain submenus won't be shown in the subframe - they will be shown in the frame with the top-menu.
It's caused by a security policy of browsers - a script can't modify a content of pages from another domain.
