Here are the steps outlined in this video.

Auto Expand Drop Down List
1) Select cell E3
2) =UNIQUE(SORT(FILTER(D3:D20,NOT(ISBLANK(D3:D20)),"NA")))
3) Enter
4) Select cell B2
5) Data ~ Data Tools ~ Data Validation ~ Data Validation
6) Allow set to List
7) =$E$3#
8) OK

Let's breakdown the formula.
=UNIQUE(SORT(FILTER(D3:D20,NOT(ISBLANK(D3:D20)),"NA")))

'FILTER(D3:D20, NOT(ISBLANK(D3:D20))): This part filters the range D3:D20 by removing any blank cells. It only returns the non-blank cells from that range.

SORT(FILTER(D3:D20, NOT(ISBLANK(D3:D20)))): The SORT function sorts the non-blank cells obtained from the previous step in ascending order.

UNIQUE(SORT(FILTER(D3:D20, NOT(ISBLANK(D3:D20))))): The UNIQUE function then takes the sorted non-blank cells and removes any duplicates. It returns a list of unique values from the sorted list.

Finally, "NA" is used as the third argument for UNIQUE to specify how to handle error values. In this case, it means that if any error occurs during the calculation, the function will return "NA" as the result.

So, the overall purpose of this formula is to create a list of unique, sorted values from the range D3:D20, excluding any blank cells, and handling any potential errors with "NA" as a result.
