Boolean expressions in the where statement

Im trying to build a form with multiple check boxes that each apply a filter
to the records displayed. I need for the user to be able to select any
combination of the checkboxes and have the resulting records filtered
accordingly.

I was thinking something along the lines of a "select" or statement or an
if...else loop, but unfortunately im fairly new with sql am having trouble
with the syntax, assuming its even possible.

Something along the linse of:

Select * from Table Where
If (chkA = true) then chkA
Else (chkB = true) then chkB
else (chkA = true) and (chkB = true) then chkA and chkB
else *;

Any help would be greatly appreciated.
