Excel 2000 ... Earlier today I saw a spread sheet that
had what appeared to be a Filter Switch in a Cell.

When cell with switch selected ... switch listed 2 values
to choose from (Y or N) ... In addition, as different
cells (requiring same Y or N value) were selected the
switch moved to selected cell.

Above said ... how is this all accomplished as I wish to
replicate this capability on another spread sheet?

Thanks ... Kha
