title: Hide columns in excel based on drop down list selection
body: <p>I am wondering if it is possible to hide columns based on the selection of a drop down list using excel.
  For example say i have 3 columns( C1,C2,C3) and i have a drop-down list with 2 values(drop1 and drop2). When drop1 is selected from the dropdown list then show C1,C2 and hide C3. When drop2 is selected show all Columns C1,C2,C3 . Does anyone know if this is possible in excel ?</p>
