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: Can I just ask what the maximum KB size should be for a Data.js file for a webpage?
At the moment Vehicle_data_2.js is 24.7KB and growing as I add more data, what would you recommend as the largest size to sensibly use?
A: 24.7KB is the normal size of the file. But if you think that it isvery large you can try to use AJAX-technology to divide this file.

Q: I need a navigation bar dhtml where on the click of certain items, server side code on the page can be called and executed.
I need to create a multiple item select menu. Sothe menu would need to remain open and allow a user to selectmultiple items and would either submit onmouseout or maybe a “submitthese selections” menu item.
A: You can try to use Deluxe Tree in that case:

You can paste any html code inside item text, see example here:
http://deluxe-tree.com/data-samples/tree-menu1.js
["+Support", "", "icon5_t.gif", "icon5_to.gif", "", "Support Tip"],
["|Index <select style='width:120px;height:17px;font:normal 10px Tahoma,Arial;'><option>Section 1<option>Section 2<option>Section 3</select>", "", "", "", "", "","", "0"],
["|Search <input type=text style='width:80px;height:17px;font:normal 10px Tahoma,Arial;'> <input type=button value='Go'style='width:30px;height:17px;font:normal 10px Tahoma,Arial;'>", "", "", "", "", "", "", "0"],
["|Write Us", "mailto:[email protected]", ""],
["|<INPUT TYPE=checkbox CHECKED ID=chk1 onclick='choosebox1()'>Uncheck this check box for some free advice","","","",],
["<img src='img/sep.gif' width=113 height=1>"],
You should also add your own code, so your checkbox will workcorrectly.Q: I've been trying to get the menu item in dynamic tree menu to stay highlighted when clicked on and directed to that page.
A: Tree Menu doesn't save a presseditem as it saves a tree state.
It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function apyt_ext_setPressedItem(menuInd, itemID)
<script type="text/javascript">
var i = 4 //index of the selected item
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
To expand specific items you should use the following function:
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 11), 1);
