oj-tree-view expand all performance guidelines

Summary:

We have implemented oj-tree-view with 4 levels of child nodes and huge data set of appx 50+ parent nodes. As per documentation expanding all nodes for huge data set is not advisable , as it effects the performance.

Please provide some pointers for expanding nodes with the below 2 alternate approaches ,

1) Recursively expand nodes - similar to pagination 1-10,10-20,... 40-50 and traverse the tree.

2) On click of the Parent node expand all the child nodes for that parent until the leaf node is reached .(By default user has to click on each node at each level to expand till leaf nodes are reached).
