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: I haven’t had any problems using the drop line menu, until now when I had to make some changes. After adding some sub-menu items on two of the drop line menu buttons, those menu’s drop down upwards, instead of downwards like the rest. I tried deleting them and remaking them, but then the menu appeared to have no image behind it, only a colour. So I duplicated a working menu item, and then modified it to be what I wanted – and it still drop down upwards!
A: Please check the following drop line menu parameter:
var subMenuVAlign="top";
Q: I have noticed on your menus that have multiple nodes, you areallowing only the icon to be clicked and expand the tree. How would I alter the code so that when a user clicks anywhere on the tree with multiple nodes, the entire tree expands instead of the user having to be so precise in selecting the tiny icon to expand the tree.
A: You should set the following parameter to expand item on a mouseclick:
var texpandItemClick=1;
Q: How do I make the buttons in my java navigation menu transparent?
I only want to see the letters appear in my table and not the button until I mouse over it?
A: To set transparent background for the menu you should set:
var menuBackColor="transparent";
var itemBackColor=["transparent","transparent"];
