Hover on one div to display another div

Cracking for a whole day now and still couldnt find a simple solution to this problem.

I have a class

  .displaynone{
      display:none;
    }

I am trying to

  1. Hover on #hoversubheader1 and display #subheader1 by removing .displaynone on #subheader1.
  2. Do not allow #subheader1 to disappear when I move my mouse from #hoversubheader1 into #subheader1
  3. Add back that class to #subheader1 when my mouse is in neither #subheader1 nor #hoversubheader1.

Have yet to accomplish step 2 and 3.

I know you will want me to nest the elements, but I have reasons to not do so. In reality the two divs are separated by some 'space', so naturally I might need a setTimeout or other timing related functions for this but am also not sure if I am on the right track.

Would make my day if someone could help on this.

JS

    (function($) {
    "use strict"; // Start of use strict
    //header hover brings out subheader bar
    $("#header").hover(
      function () {
        $("#subheader").removeClass("displaynone");
      },
      function () {
        $("#subheader").addClass("displaynone");
      }
    );
    //hovering on each subheadertitle should display each subheader1, subheader2 etc
    $('#hoversubheader1,#subheader1').mouseenter(function(){

        $('#subheader1').removeClass("displaynone");
    }).mouseleave(function(){

        $("#subheader1").addClass("displaynone");

    });

    $('#hoversubheader2,#subheader2').mouseenter(function(){

        $("#subheader2").addClass("displaynone");

    });
    }(jQuery)); // End of use strict
