overflow: hidden problem in table header with bootstrap dropdown

Hi,

As part of my table header I am displaying a bootstrap dropdown. The problem is that the list is shown only in the header area, but cut when it continues with the body. This is because of the "overflow: hidden" of the .dataTables_scrollHead. Any idea how can I workaround this? I want my dropdown lists to display fully (that is, continue in the body area).

Thanks in advance,
