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: Thank you for such an excellent product. I have a question pertaining to the submenu items in your tree-menu line. My menus are 540px wide and contain lots of text with good sized pictures (icons). Can I use an iframe tag inside of the css menu submenu instead of simple text with this icon?
A: You are able to paste any html code within items.
So you can paste a form too.
For example:
var menuItems = [
...
["||<nobr><FORM method=GET action='http://www.google.com/custom'><input name='as_q' value='search
the web' size=15 style='font-size:10'> <INPUT type=hidden name=cof
value='LW:144;L:http://domain.edu/images/sulogo.gif;LH:45;AH:center;GL:0;S:
http://domain.edu;AWFID:e01cb67b8afe383e;'></form></nobr>","",
"images/icons/search.gif", "", "", "", "", "2", "", "", "",],
Q: Cross-frame mode/ showByClick=1: I only want this to work on the main level javascript menu bar, not the submenus. Is there anyway to showbyclick only for the main level and then not for the submenus?
A: You can use Individual Item Styles to set showByClick parameter forthe top items only.
var itemStyles = [
["showByClick=1"],
];
Q: I'm using the deluxe-tree; my dynamic tree menu is very long; and the page has a vertical scroll bar as a result. My question is, does the dynamic tree menu support anchors? So let's say I do mypage.aspx#mynode, and mynode is a tree-node, and happens to be on the bottom of the page, can we make it so that the user goes to that node, without him using the vertical scroll bar?
A: No, it is not possible.
But you can collapse your tree menu by default:
var texpanded=0;
and use API functions to expand the specific items based on the page you are now:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>
