             Summary: Allow only tree node to be expanded if there is a large number of routers 
                 Key: DISPATCH-552
                 URL: https://issues.apache.org/jira/browse/DISPATCH-552
             Project: Qpid Dispatch
          Issue Type: Improvement
          Components: Console
            Reporter: Ernest Allen
            Assignee: Ernest Allen


There is a navigation tree on the left of the Overview and Entities pages. 
Management calls are periodically made to update the data for each node in the tree that is expanded .

The amount of data requested becomes problematic when there is a large number of router in the network:
- It takes a long time to retrieve
- It takes a lot of memory to store
- It uses bandwidth

For large networks, the expand all/collapse all arrows at the top of the tree should be hidden and expanding a tree node should automatically collapse the other nodes.
