There is no need to use jquery to build the tree. You can simlpy build the tree by using html and some + image sybol. you can control in the code to what leve you want to show the tree. Normally we uses recursive loops to build the tree. Whenever there is leaf node we add dot image and whenever there are children under it we can add + image symbol.
