Select (expand) a dropmenu when clicking on another element
===

I have a div containing a select menu and another element (*.dropArrow*).

What I would like to do is select the menu when you click on .dropArrow.

Here's the jquery I've tried so far but with no success...

    $(".dropArrow").live('click', function() {
    	$(this).siblings("select").click();
    });

HTML

    <div class="selectContainer selectTest" style="width: 305px;">
        <select id="selectTest">
            <option value="1">1</option>
            <option value="2">2</option>
            <option value="3">3</option>
            <option value="4">4</option>
        </select>
        <span class="dropArrow">^</span>
    </div>

I'm guessing it's the .click() part that's wrong as I can change that to something like .hide() and it works fine.
