Recent Questions Dropdown Menu Folder Tree Style
Q: I'm loving your product! It has definitely made my life easier.
I do have a question however. I know if I put a "+" in front of the title, the category will be expanded by default.
["+PRODUCTS","", "", "", "", "", "", "", "", ],
Is there a way to do that dynamically? Maybe have some code that would tell the sliding tree menu to expand on that particular page?
A: On your pages you should call the following function/functions to expand/highlight items, for example:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>

http://www.deluxe-tree.com/functions-info.htmlQ: 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>

Q: I have started using your menu and when testing in both IE-browsers the CPU jumps to 100% for at least 30 to 60sec.
Then the sub menu appears but also not as fast as in Firefox(no effects).
Now does my menu contains about 1476 item-lines, and I use the cross-frame modus.
Any ideas?
A: It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
JavaScript Tree Menu works fast, but 1500 is a large value.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
You can try to use AJAX-like technology.
