You could track the items in the view when create and use the suicide() function.

CODE

this.myobject.suicide();

Thank you for your help. However I got an error, it says suicide is not a function. Here is my code, "cs_tree_menu" is the id of my treeview.

CODE

var tree = document.getElementById("cs_tree_menu");
tree.suicide();

suicide is a wrapper method, it's not available on the dom element. Do this instead:

CODE

var tree = $("cs_tree_menu");
tree.suicide();

By the way, we don't use YUI, we use KONtx.

Ops, I guess I am in the wrong forum. I am using YUI to build an application front page. Thank you everyone for your help. I am using Javascript and YUI, if anyone know how to remove treeview using Javascript or YUI, please I need your advise.
