how to create drop down button like gmail "move to" button?

i have a simple file upload system coded in php.

As part of increasing the UI simplicity, i want to have a similar gmail "Move To" button where I can check multiple checkboxes and then after clicking one of the many possible entries in the drop down generated by the button, some postback takes place.

Ple开发者_开发百科ase advise.

Thank you.

Ideally, would be to use jQuery. though i am not an expert, i have some small experience using jQuery.

I use jQuery Multiselect to do something similar.

A bit late but there is my button with drop down option list solution using JQuery UI:

Working solution in jsfiddle

html:

<button id="menuButton">Menu Button</button>
<ul style="z-index: 9999999;position: absolute;" id="menuElement">
    <li><a href="#">Select Green</a>

    </li>
    <li><a href="#">Select Red</a>

    </li>
    <li><a href="#">Select Gray</a>

    </li>
</ul>

code:

var $menuButton = $("#menuButton");
var $menuElement = $("#menuElement");

$menuButton
    .button({
             icons: { 
                       secondary: "ui-icon-triangle-1-s"                 
                    }
            })
    .click(function (event) 
              {
                 $(document).one("click", function () 
                    {
                       $menuElement.css("visibility", "hidden");
                    });

                $menuElement.css("visibility", "visible");
                event.stopPropagation();
             });

$menuElement
    .menu({
             select: function (event, ui) 
                        {
                           $menuElement.css("visibility", "hidden");
                        }
         })
    .css("visibility", "hidden")
    .position({
                 my: "left top",
                 at: "left bottom",
                 of: $buttonElement
              });
