Sortable and href link

I have sortable div #container that consist divs. There are links in
this divs. And all works fine but link in the first div doesn't work.
Only in first. If i drop on the first place other div, it's lint will
not work.
What do i do to fix it?
If it can't be fixed, may be there some way to make draggable for
sorting only some part of sortable divs?
