jQuery UI Multiselect

I've merged some of the pull requests from the original author's repo to make this plugin useable for me.

If you submit patches I'll try be a little more on top of maintaining them.

Options (default)

• sortable (true) : enable sorting the selected items.
• dragToAdd (true) : enable adding selected items by dragging.
• searchable (true) : enable searching for available items.
• doubleClickable (true) : enable adding selected item by double clicking.
• animated (fast) : animation option.
• show (slideDown) : show effect.
• hide (slideUp) : hide effect.
• dividerLocation (0.6) : the ratio of the size of the left column versus the right column.
• selectedContainerOnLeft : controls which side the selected container is on.
• width (null) : width of widget.
• height (null) : height of widget.
• nodeComparator : the function for comparing nodes.

Example

<!--HTML-->
<select class="multiselect" multiple="multiple" id="colors" name="colors">
    <option value="red">Red</option>
    <option value="blue">Blue</option>
    <option value="green">Green</option>
</select>

//Javascript: setup multiselect.
$("#colors").multiselect({
    dividerLocation: .5
}).change(function (e) {
    //output values.
    console.log($('#colors').val());
});

• Updated so width doesn't expand past what the target elements width is. Borders were causing this to happen.
