In the above example Mike is the first level and Alice is the first child of MIKE when i add another child for MIKE with the same name as ALICE it s not showing. How can Solve this issue?

I didnt find a Great answer but It worked for me. given a space for the second name and it worked.

i.e

data.addRows([
          [{v:'Mike', f:'Mike<div style="color:red; font-style:italic">President</div>'}, '', 'The President'],
          [{v:'Jim', f:'Jim<div style="color:red; font-style:italic">Vice President<div>'}, 'Mike', 'VP'],
          ['Alice', 'Mike', ''],
          ['Alice ', 'Mike', ''],
          ['Bob', 'Jim', 'Bob Sponge'],
          ['Carol', 'Bob', '']
        ]);

For the second 'Alice ' after the name I given a space. Which worked.
