Consider the Mathematica function Manipulate where you assign the placement of the controls with the option parameter ControlPlacement, i.e.

ControlPlacement -> Top

Now assume I want to create a function f:

f[x_, option_] := ( ... )

That is, I assume this is the way to define the functionality I require.

I want the option parameter to have values from

opts := {1 -> "A", 2 -> "B", 3-> "C", 4-> "D", 5-> "E"}

such that when I enter the function that when I type option, a dropdownlist appears showing A, B, C, D and E.

How do I create this functionality for a function?

I don't think it is, as suggested in the comments, custom completion ( which is still being developed for version 12.+ ).

I think this is covered quite well in the documentation https://reference.wolfram.com/language/tutorial/SettingUpFunctionsWithOptionalArguments.html – mikado Aug 29 '16 at 11:06

Is this what you need? Prompt a set of possible options – Kuba Aug 29 '16 at 11:25
Sounds like you want this feature, which is not yet part of the release version. Or did it get another name? – Karsten7 Aug 29 '16 at 11:47
How can it not be in the release yet if 'Manipulate' itself has it? – nilo de roock Aug 29 '16 at 12:39
@Kuba thanks will look at that – nilo de roock Aug 29 '16 at 12:39
I don't quite understand why do you want. "...when I type option, a dropdownlist appears showing A, B, C, D and E." - what do you mean by type option, and assuming e.g. 1, why would other characters appear on a dropdown? – Kuba Aug 30 '16 at 13:08
@Kuba can you please provide the code you used? I am just confused about this particular functionality of Mma. Thanks. – nilo de roock Sep 01 '16 at 10:25
What code? I haven't done anything. I'm just asking how the feature you are talkin about differes from the linked one and I ask about calrification of doubts I have. – Kuba Sep 01 '16 at 10:31
You said "when I type option, a dropdownlist appears showing A, B, C, D and E." so how did you do that? That's all I am asking. – nilo de roock Sep 01 '16 at 10:39
@niloderoock you said that, that is why I've used quotes... – Kuba Sep 01 '16 at 11:06
You leave me completely in the dark, @Kuba – nilo de roock Sep 01 '16 at 11:20
"...when I type option, a dropdownlist appears showing A, B, C, D and E." - thse are your words, have you read your post? :) – Kuba Sep 01 '16 at 11:22
