Heading selection in one cell corresponds to another its items in another cell

[snkhan]

Hello Everyone,

I need a bit of help. I have a few columns on one worksheet (sheet2); it has headings(A1-C1) and corresponding items below it (A2 - and downward). Now I want a drop-down selection on Sheet1 at A2 and when I select a particular Heading Say(A1 Heading), I want the corresponding items list of that heading to show up in the cell(B1). I have attached a sample of how it should look like. Any help would be greatly appreciated. Thank u in advance.
best regards,
