I am using simple jquery popup and Auto complete of [jQuery Auto complete](http://jqueryui.com/autocomplete/) .The code of Auto complete is something like this.

```
$("#tags").autocomplete({
    source: NameArray
});

```

where tags is the textbox id and NameArray is Array of string.However this code in the Modal pop-up like this-

```
function openFilterPopUp() {

    $("#tags").autocomplete({
        source: NameArray
    });
    $("#openFilterPopUp").dialog({
        resizable: false,
        height: 240,
        modal: true,
        buttons: {
            "ok": function() { $(this).dialog("close"); },
            Cancel: function() { $(this).dialog("close"); }
        }
    });

}

```

The data for Autocomplete is appearing fine but its appearing behind the popup.Please Help. Any help will be appreciated.
