Comment (by punit5658):

 I like to work on this ticket. To achieve solution to reduce parent -
 child menu tree. I have suggestion to add one icon i.e. ( + ) and ( - )
 for small.  We can change icon if any suggestion. By click on icon child
 menu will be hidden and get back visible on click again replace icon at
 same place.
 Let me know if anyone can have more option.

 One more improvement suggestion is : we can add like option icon which is
 contain multiple icons i.e. collapse/expand, show/hide ( here show hide
 can help immediate hide menu from menubar by adding class in frontend, no
 need to create multiple menu for single change ). Give me feedback for
 second option.
