DHTMLGRID Filters.. hide/display from a button

Hi all… I am looking to build an DHTMLGrid for a portlet implementation.
I would like the “header filters” to not show as a default… ie a one line header
with just the column headings then when the user wants to filter… they can click a button
from above the column headers and the defined column filters appear…
and click again and they go away…

is this possible with DHTMLXGrids…
has anyone done something similar…

Thanks in advance…

Partially. I have been able to use the attachHeader and removeHeader grid methods to show and hide the filter header rows. But removing the header does not seem to clear the filter, and once I reattach the header, the values in the filter do not seem to function. There does not seem to be a built in function for doing this according to the API.
