[jQuery] ui selectable

[jQuery] ui selectable

Hi All,
I am making a AJax File Manager using jQuery and a bunch of plugins within the interface
I am having some trouble with selectable
here is my code (from within a document ready block)
        $("#iconScroller > div.folder, #iconScroller > div.file").selectable();
here is my mark up
            <div id="iconScroller">
                <div class="folder">
                   

test


                </div>
                <div class="folder">
                   

test2


                </div>
                <div class="folder">
                   

test3

</div>
                <div class="folder">
                   

test4

</div>
            </div>
can you make selectable divs?
2nd question is it possible to combine selectable & draggable?
thx - S
