Q: we want to be able to specify a certain height (or number of items) for the main menu after which a new column is created.
A: Unfortunately it is not possible to specify a number of items after which a new column is created.
But you can use blank items and create Individual Style for theseitems.
For example:
["| ","", "", "", "", "", "0", "", "", ], //empty item
["|Item 42","", "", "", "", "", "", "", "", ],
["| ","", "", "", "", "", "0", "", "", ], //empty item
["|Item 44","", "", "", "", "", "", "", "", ],
Q: I evaluated JavaScript Tree Menu over the weekend and I really like it. I believe I'll be buying it this week. I have one question. Is it possible for the menu to be aware of what page you have selected and highlight the corresponding menu item on that page.
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.
Q: Is it possible to insert a dhtml foldout menu item at the top of the submenu? For example, if a dhtml foldout menu is defined as:
var menuItems = [
["Search","","","","","","1","0"],
["|Residential","srch.php","","","","","0"],
["|VacantLand","srch.php?cri","","","","","0"],
["|Commercial/Industrial","srch.php","","","","","0"]];
How can I add a new item above “Residential?” I’ve tried the following with no luck — the forth argument does not seem to be used:
dm_ext_addItem(0, 1, ["New Sample", "testlink.htm", "", "", "Your Sample Tooltip", "middle", 0], 0)
A: To insert item in the specific position you should use thefollowing function:
function dm_ext_addItemPos (menuInd, submenuInd, iParams, Pos)
Q: Do you have an extremely simple example of modifying a dynamic drop down menus with the JavaScript API? I've played with the example on the site, but I have trouble removing the other menus without breaking it.
I just want to use the API to change the icon on the menu items.
A: You should use the following function:
function dm_ext_changeItem (menuInd, submenuInd, itemInd, iParams)
<script language="javascript" >
dm_ext_changeItem(0, 0, 1, ["", "", "new_icon.gif", "new_icon_o.gif", "",,""]);
</script>
