Can u suggest me how to implement this..?

Sure! :-)

You want look into how to collapse tree nodes in D3 v4. Basically you create a listener on clicking that removes or hides all the children nodes when a node is clicked, then you re-render the tree.

Here is an example:

Make sure that your listener on clicking doesn't interfere with the dTree click callback.

We also want to add an option flag called "collapseOnClick" that controls the behavior. I think that the default behavior should be that the flag is set to false. Something like this:

{
  target: '#graph',
  debug: false,
  width: 600,
  collapseOnClick: false
  // the rest of the options are excluded..
}
