JSF doesn't come with a tree GUI control because core JSF is mapped to plain HTML and there's no basic HTML tree control. However, some of the third-party extension tagsets do provide a tree control.
As far as jQuery goes, jQuery works quite well in a JSF environment. In fact, some of the third-party packages use jQuery internally.
There are 2 things, however, that you have to be aware of when using jQuery in JSF.
1. Element IDs at the jQuery level (raw HTML) are not the same as their JSF source-code IDs. For example the inputText control with an ID of "firstName" in a JSF form named "form1" will have an HTML (jQuery) ID of "form1:firstName".
2. The "$" character has an alternative meaning to the JSF EL processor. So instead of using the common jQuery "$" form, you have to use the "jQuery." form of expression in order to avoid conflicts and confusion.
