Add item to drop down box

[collinsc]

Hi

I have a worksheet with a drop down box in the first row of columns. The options in the drop down box are "all" "top 10" and "custom".

I would like to add my own word so i can filter by it.

For reference, the word is "build".

Thanks

I have done this now.
for reference what i had to do was>
select the columns i wanted to include filter words from>
select data>
select filter>
deselect autofilter>
reselect autofilter.
then the words are added.
