Q: I would like when I click on what ever link of the php dhtml menu that the visited link stay in a different color and with a different background
A: Javascript/DHTML Tree doesn't save a presseditem as it saves a tree state. It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function dtreet_ext_setPressedItem (menuInd, itemID)
Please, see here:

You can also set
var tsaveState = 1;
More info you can find

To expand specific items you should use API functionfunction dtreet_ext_expandItem (itemID, expand)
Q: Typically in order to generate a menu with multiple layers I’d put a pipe character in front of the menu text.. For example:
["|Page Admin","/admin/handoutadmin.php", , , , "_new", , , , ],
["||Student Pages","/admin/handoutadmin.php?type=1", , , , "_new", , , , ],
["||Teacher Pages","/admin/handoutadmin.php?type=2", , , , "_new", , , , ],
["||Family Letters","/admin/handoutadmin.php?type=4", , , , "_new", , , , ],
["||Transparencies","/admin/handoutadmin.php?type=3", , , , "_new", , , , ],
However, when I try to do it with dm_ext_addItem it actually SHOWS the pipe character and doesn’t create any menu levels at all.
For example:
dm_ext_addItem(0, 0, ["Add a Handout to this Lesson", "", "", "", "", "", ""]);
dm_ext_addItem(0, 0, ["|Student Page","/admin/handoutadmin.php?type=$type", "", "", "", "_new", ""]);
dm_ext_addItem(0, 0, ["|Teacher Page","/admin/handoutadmin.php?type=$type", "", "", "", "_new", ""]);
How can I generate multiple levels of the menu with javascript?
A: I suppose that your code is not valid
dm_ext_addItem(0, 0, ["|Teacher Page", "/admin/handoutadmin.php?type=$type", "", "", "", "_new", ""]);
Try to write it in the following way:
dm_ext_addItem(0, 0, ["|Teacher Page", "/admin/handoutadmin.php?type=", "", "", "", "_new", ""]);
Q: When I create a tab which has no sub-items, there is a white line drawn under the whole top javascript tabbed menu bar.
How do I avoid this?
A: Each menu item should have subitems (in the TabMode).
If you don't want to have subitems for some items you can add onesubitem and delete Item Text.
["Item 2","", "", "", "", "", "", "", "", ],
["|","", "", "", "", "", "0", "", "", ],
Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Javascript/DHTML Tree such as in JavaScript Tree Menu.
6. 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/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Javascript/DHTML Tree into the <table> or <div>.
