I have the follow structure which is created with a nested sortable:

<UL id="container">
    <LI id="main1">
        <input type="checkbox" />
        Lorem ipsum dolor sit amet, consectetur 
        <UL>
            <LI id="child2">
                <input type="checkbox" />
                In hac habitasse platea dictumst. 
                <UL></UL>
            </LI>
        </UL>
    </LI>
    <LI id="main3">
        <input type="checkbox" />
        In hac habitasse platea dictumst. 
        <UL></UL>
    </LI>
    <LI id="main4">
        <input type="checkbox" />
        In hac habitasse platea dictumst. 
        <UL></UL>
    </LI>
    <LI id="main5">
        <input type="checkbox" />
        In hac habitasse platea dictumst. 
        <UL></UL>
    </LI>
</UL>

Where I'm stuck is how to send this back to the database. I"m guessing that it needs to be serialized, does that sound right to?

so that is looks something like:

item[]=main1&item[]=221&item_221[]=21&item_221[]=2&item_221[]=211&item[]=22

I'm a little lost at this point and appreciate any tips to move me in the right direction.

Thanks,

B
