collapse tree when it appears

[reviliell]

Thank you for such a nice nav-tree.
I'm not really good at js and have a question:
function loadCompleted(result) { $scope.tree = result.data; $scope.tree_ctrl = {}; }
Here is my function for success webApi data request and my tree is look good but i want it will be collapsed, when it appears
When i'm doing a button with ng-click="tree_ctrl.collapse_all()" - it works ok, but i can't collapse my tree when it appears
Could you help me how to do it?

I guess you only need to wait for the tree to be rendered with angular and then command it to collapse or expand.
So this should work $timeout(function(){$scope.tree_ctrl.expand_all();});
