Q: Can I use javascript to get the object (getElementByID). If not howdo I hide my dropdown menu on print?
A: You can add a new button to print your page and call onClick event, soyou should write:
<body ....
onClick="document.getElementById('dm0m0').style.visibility='hidden'; window.print();">
...
</body>
Or you can use the same javascript code from your menu item.
For example:
var menuItems = [
["Print", "javascript:document.getElementById('dm0m0').style.visibility='hidden';
window.print();", icon1, icon2],
];
But if you want to hide the menu when your customers push "File/Print"you should write so:
You must create two functions, for example:
function myprint()
{ document.getElementById('dm0m0').style.visibility='hidden';
window.print();
}
function myprint2()
{ document.getElementById('dm0m0').style.visibility='visible';
window.print();
}
You should add this functions into your code.
And then you must write so:
window.onbeforeprint = myprint;
window.onafterprint = myprint2;
Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: This is probably a really basic question, but I was wondering if
your dhtml menu maker makes it possible to determine the direction of the
drop down menu. In other words, my menu is at the bottom of the page
and I want the drop down list to actually go "up," not down.
Is that possible with your software?
A: Yes it is possible.
You should use the following parameter
var subMenuVAlign="top"; //downward
var subMenuVAlign="bottom"; //upward
var subMenuAlign="left"; //from left to right
var subMenuAlign="right"; //from right to left
Q: Thank you for your prompt replay- the menu now works! However, the multi level dhtml menu takes forever to load up as demonstrated on our website. I was wondering whether there was any possible way of getting it to load up faster.
A: I have noticed no delays in the menu loading.
But your menu is big enough. You can try to us AJAX technology.

Try to set the following parameter also:
var dm_writeAll=1;
