Q: I see that you have the demo of the menu working over a frame so that it displays over the lower frame, vertical top to bottom.
However I have played around with your demo and can't seem to replicate the same feature.
Could you please tell me what I have to set to make the easy dropdown menu float over the lower framed window?
A: To initialize the cross frame menu call dm_initFrame() function instead of standard dm_init() function within data.js file:
dm_initFrame(framesetID, mainFrameInd, subFrameInd, orientation);
framesetID - id attribute of the frameset;
mainFrameInd - index of the main frame (where the top-menu is placed), >=0;
subFrameInd - index of the subframe (where the submenus will be shown), >=0;
orientation - frame orientaion: 0 - top-to-bottom, 1 - left-to-right; 2 - bottom-to-top; 3 - right-to-left.
For example, for the following structure:
<frameset id="frmSet" rows="185,*">
<frame id="frame1" src="cross-frame-horizontal-1.htm">
<frame id="frame2" name="testlink.htm" scrolling="no">
</frameset>
the dm_initFrame() function call at the end of data.js file will look like:
dm_initFrame("frmSet", 0, 1, 0);
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: When I put any new link on my tree view expand it goes as if I am placing as _blank when I have it leading to _self.
A: At the moment you have:
var titemTarget="_blank";
And you haven't specified "_self" parameter to
["||Unilock Fireplace MODS","fireplace_unilock_mods.htm", "", "", "", "", "", "", "", ],
You should set
var titemTarget="_self";
or set "_self" parameter for each item individually:
["||Unilock Fireplace MODS","fireplace_unilock_mods.htm","", "", "", "_self", "", "", "", ],
Q: One other question, how do you get the menu bar to highlight and stay on the page you are viewing rather than highlighting home the whole time.
A: You should 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.
