Use e.stopPropagation(); when click on table and hide menu on click the all window :

 $(document).ready(function () { $(".my-table").click(function (e) { if($(".menu-header2").length>0) $(".menu-header2").show(); e.stopPropagation(); }); $(window).click(function() { $(".menu-header2").hide(); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="menu-header2"> <ul> <li>upload</li> <li class="itemMenu hide"><a href="#">download</a></li> <li class="itemMenu hide"><a href="#" >delete</a></li> </ul> </div> <table class="table my-table"> <thead> <tr> <th>name</th> <th>size</th> </tr> </thead> <tbody> <tr> <td>word2016</td> <td>574 KB</td> </tr> <tr> <td>power2016</td> <td>574 KB</td> </tr> </tbody> </table> <script> </script>

Use event.stopPropagation()

 $(document).ready(function() { $(".my-table tbody > tr").click(function(e) { //if (e.target !== this) { // $(".menu-header2 .itemMenu").removeClass("show").addClass("hide"); // } var item = $(this); item.addClass("selected2"); $(".menu-header2 .itemMenu").removeClass("hide").addClass("show"); $(".my-table tbody > tr").not(item).removeClass("selected2"); }); $('.my-table').click(function(e) { $('.menu-header2').show(); e.stopPropagation(); }); $(window).click(function() { $('.menu-header2').hide(); }); });

You want when you click in the tr all li are hide when you clikc outside of tr the li are show. ok? so you want this codes:

 <table class="table my-table"> <thead> <tr> <th>name</th> <th>size</th> </tr> </thead> <tbody> <tr> <td>word2016</td> <td>574 KB</td> </tr> <tr> <td>power2016</td> <td>574 KB</td> </tr> </tbody> </table> 

 var item = document.getElementById("i1"); var item2 = document.getElementById("i2"); function hide() { item.style.visibility = "hidden"; item2.style.visibility = "hidden"; } function show() { item.style.visibility = "visible"; item2.style.visibility = "visible"; } 

 <div class="menu-header2"> <ul> <li>upload</li> <li class="itemMenu hide" id="i1"><a href="#">download</a></li> <li class="itemMenu hide" id="i2"><a href="#" >delete</a></li> </ul> </div> <table class="table my-table"> <thead> <tr onclick="hide()"> <th>name</th> <th>size</th> </tr> </thead> <tbody> <tr onclick="hide()"> <td>word2016</td> <td>574 KB</td> </tr> <tr> <td onclick="show()">power2016</td> <td onclick="show()">574 KB</td> </tr> </tbody> </table> 

If you click on the namr or size or word2016 or 574KB the download and the delete is hide but if you click on the powe2016 or othe 574 KB the delete and download are show. please read the function hide() and function show()
