canonical way to have multiple columns use ui.selectable?

canonical way to have multiple columns use ui.selectable?


I have a table containing lists like this
<table>
<tr>
<td>
<ol id="my_sort_id1">
<li> blah </li>
<li> blah <li>
</ol>
</td>
<td>
<ol id="my_sort_id2">
<li> more blah </li>
<li> more blah </li>
</ol>
</td>
<!-- etc etc etc -->
</tr>
</table>
I want to attatch selectables to any of the lists in the table
1) Do I have to use an id or can I use a class instead?
2) Can I send a variable id or classname to the initialisation
function ?
any help gratefully received
