exclude certain rows?? also, limit size and range select option

[arjunmenon]

hey

i know too many request, but yours is a perfect, sleek way to sort table.

is it possible to exclude certain rows from the dropdown filter.
i have an application which has hidden rows beneath a row, which comes in to view when onClick.
is it possible to hide those hidden rows appearing in the dropdown value.

also, is it possible to limit height/size of the dropdown. for eg,total 10, show 5 elements and scroll for rest.
and anyway to add option to sort column up and down inside dropdown.
how to add price range slider, if you have a price column.

thanks
