Example:

<select id="e1">
    <option value="cheese">Cheese</option>
    <option value="tomatoes" selected>Tomatoes</option>
    <option value="mozarella">Mozzarella</option>
</select>
<select id="e2">
    <option value="mushrooms">Mushrooms</option>
    <option value="pepperoni">Pepperoni</option>
    <option value="onions" selected>Onions</option>
</select>

$('#e1').multiselect();
$('#e2').multiselect();

This properly selects Tomatoes for e1 and Onions for e2. However, expanding the dropdown for e1 shows the radio has been deselected, despite the background color staying active:

You can continue the chain as long as you want... If I had repeated those 10 times, only dropdown 10 would have its radio selected, and the previous 9 would not.
