There are many cases when people might want to have a dropdown list of the other entered values in a column.

And the ability to prohibit entering others.

Classic one: entering yes, no, maybe.

These are not boolean, but discrete, and others should not be allowed.

Do you know how to do that?

Answer

source

select your range D25:D99, then menu Data->Validity In dialogue Validity select from drop-down list variant “Cell range”, and bottom set “Source” (your H3:H25) Push OK

Here is an example.
