title: Show and Hide Columns menu in table
body: <p>I'm building a table with large number of columns which I want to be able to show and hide from user menu. </p>
  
  <p>nice example from kendoui site <a href="http://demos.kendoui.com/web/grid/column-menu.html" rel="nofollow">here</a> </p>
  
  <p>My problem is that show/hide menu is the same for all columns, but it is buried deep inside column menu of each individual column. </p>
  
  <p>I want to have that menu only in one place, possibly in table toolbar or exposed in footer so the user does not need to click through the complex dropdowns.</p>
