Dropdown-menu to close on click outside / hover outside

Question

So I am currently working on a Dropdown-List menu and as you may suspect... I am very newbie. I wish to make it so that when I have the Dropdown-menu opened, so that when I hover or click outside of it, the dropmenu should hide again. How is it possible to make this work? I have tried a few tips here on Stackoverflow but none which are working for me sadly.

As you can see below, it is an onclick="toggle_visibility" for my dropdown menu called (ID) "droppy" It has a default display:none; so when I click on the <a> tag it opens the "droppy"/dropdown-menu. But what if it should close again when either hovering outside or simply clicking outside. Both solutions is alright for me =) If someone knows, please help. Thanks!

 function toggle_visibility(id) { var e = document.getElementById(id); if(e.style.display == 'block') e.style.display = 'none'; else e.style.display = 'block'; }

 #nav #droppy{ position:relative; left:90px; top: 17px; width: 225px; height: 150px; display:none; font-size: 25px; background-color: #304749; border-bottom: 1.6px solid black; }

 <div id="nav"> <div id="fall"> <a href="#" ="javascript:void(0)" onclick="toggle_visibility('droppy');">Menu</a> </div> <div id="droppy"> <a href="airplanes">Våra Flygplan</a> </div> </div>

Answer 1

See below code. Added click event to open menu and mouseout event to hide.

 $('#fall a').mouseout(function() { $('#droppy').hide(); }).click(function(){ $('#droppy').show(); }); 

 #nav #droppy{ position:relative; left:90px; top: 17px; width: 225px; height: 150px; display:none; font-size: 25px; background-color: #304749; border-bottom: 1.6px solid black;} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="nav"> <div id="fall"> <a href="#" ="javascript:void(0)">Menu</a> </div> <div id="droppy"> <a href="airplanes">Våra Flygplan</a> </div> </div> 

Answer 2

See this code, I have used hover event

 /* $( "#menu" ).hover( function() { $( "#droppy" ).show(); }, function() { $( "#droppy" ).hide(); } ); */ $("#menu").on("click",function(){ $( "#droppy" ).show(); }); $( "#droppy" ).hover( function() { }, function() { $( "#droppy" ).hide(); } ); 

 #nav #droppy{ position:relative; left:90px; top: 17px; width: 225px; height: 150px; display:none; font-size: 25px; background-color: #304749; border-bottom: 1.6px solid black;} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="nav"> <div id="fall"> <a href="#" ="javascript:void(0)" id="menu">Menu</a> </div> <div id="droppy"> <a href="airplanes">Våra Flygplan</a> </div> </div>

<div id="parent_div">
  <div id="drop_down">
    <ul>
      <li>your_info</li>
    </ul>
  </div>
</div>

<script type="application/javascript">
  //close on hover outside #drop_down effect
  $(document).on("mouseleave", "#drop_down", function() { 
    $("#drop_down").css("display", "none");
  });

  //close on click outside #drop_down effect
  $(document).on("click mouseup", function(e) { 
    if($(e.target).closest("#drop_down").length === 0) {
      $("#drop_down").css("display", "none");
    }
  });
</script>
