jsTree integration Mysql schema -

greetings,

i have big datasets great in hierarchy format offered jstree. after several attempts understanding of schema shy of understanding. 'left','right','position','title`,'level'

now can shed insight left, , right entries? cannot find documentation on jstree need complete project soon. relationship 'right' doubles total entries? not sure feel jstree quite intuitive design , use it.

much obliged,

-peter
