Trying to combine Sortable Demo examples for Display as Grid and Connected Lists Through Tabs

Trying to combine Sortable Demo examples for Display as Grid and Connected Lists Through Tabs

Hi all.
 
I am trying to combine two of the Sortable Demo examples.  The links are below.
 
 
I am able to take the code from the Connected Through Lists and get it to work locally fine.
 
However, when I try and add the Float attirbute to the style like the Display Grid example says, it doesn't fully work.  It does display the items as a Grid, but the issue is the div for the tab doesn't autosize to account for the list of items like it does in the Connect Through Tabs without the Float added.
 
I attached two images to show what I mean.
 
In the Lists Through Tabs version I have a style of:
 
#sortable1 li , #sortable2 li { margin : 0 5px 5px 5px ; padding : 5px ; font-size : 1.2em ; width : 120px ; }
 
And for the Display Grid version I changed it to:
 
#sortable1 li, #sortable2 li { margin: 0 5px 5px 5px; padding: 5px; font-size: 1.2em; float: left; width: 80px; height: 10px; text-align: center;}
 
Any help would be greatly appreciated.  I am sure it is something stupid I don't understand like maybe Float doesn't interact with the divs somehow and it has to be done another way.
 
Thanks,
Dan
