Pull down menus
 

I would like to have a specific pull down menu appear when an adjacent cell
has a specific code entered. I have multiple material lists but I don't want
to have to sort through the entire list every time.
Example: If I want a list of W shaped beams to be available I would enter a
'W' in the box next to the list. A named range would only be shown in the
drop down list, not the entire table.


=IF(C1="W", =WSHAPES)(C1="FB", =FBSHAPES)

Any guidance will be greatly appreciated.
