Update. I've been searching and reading all over the web and haven't been able to solve this.
One way I've read about is * Save IDs in cookie when the user expands nodes, and then re-open them on next page-load. (that would do fine if i would know how to do it :) ) I don't know how to bind the .click action to a node and do something intelligent with it * Use PHP to generate extra javascript code to load the correct nodes, based on the current url. I know how to add a node to the tree, but only static html which I've written (like in the demo). How can I add a node to the tree that is read from JSON? Also, I've read that I should use events to wait for when the JSON has been read before trying to append new node. I've only found the general ideas and perhaps a code snippet or two, but nothing on where to put that code. Again, I'm a beginner :| There must be someone that has done this. Can anyone give me more information? Have a nice day, Victor
