title: Why jQuery UI 1.10 remove jquery dialog zIndex option?
body: <p>I found the latest version of jQuery UI(1.10) remove the <code>zIndex</code> option. And it's confirmed on the jQuery website.</p>
  
  <p>It really shocked me. Please think about this:</p>
  
  <p>When we have an jqgrid, and use <code>editrow()</code> or <code>addrow()</code> to open a edit dialog to edit something, and there are many fields inside, some of which have self-defined event, such as, when you click it, it will show another jQuery dialog to show some treeview items to chose.</p>
  
  <p>Under jQuery UI 1.9 (included), you can set the jQuery dialog's <code>zIndex</code> option to bigger than the jqgrid edit dialog's (jqgrid edit dialog support set <code>zIndex</code>), so the jQuery dialog always be upon and could be seen and used. </p>
  
  <p>Under jQuery UI 1.10, you cant set <code>zIndex</code>, so the jQuery dialog is always behind the jqgrid edit dialog.</p>
  
  <p>I think such scene is very common.</p>
  
  <p>Why jQuery UI 1.10 remove jQuery dialog <code>zIndex</code> option? How to control the <code>z-index</code> order when there is more than one dialog?</p>
