How can we expand the tree to maximum 3 levels down on loading

[Olivier Grimard]

I've got my initial tree populated by a JSON/Ajax call just fine but I
want to expand all nodes to a specific level.
For example, I would like to be able to expand my tree to maximum 3
levels down on loading

Any suggestions or example?
Thanks.

.bind('loaded.jstree', function(e, data){
/**
* Open nodes on load (until x'th level)
*/
var depth = 3;
data.inst.get_container().find('li').each(function(i) {
if(data.inst.get_path($(this)).length<=depth){
data.inst.open_node($(this));
}
});
})

...maybe there are more elegant and faster ways to do that, but this
should work.

works great.  If you are using jquery, just use this with out $.
