training microsoft excel - Excel formatting/Formular

Hi Mailin

Thank you for your question.

The dropdown arrows for the autofilter will show each unique item in the column below.

If not all of the items in the column show in the dropdown list, it might be because there is a blank row or rows that occurs somewhere in the list area.

Otherwise if you are meaning that you want to be able to filter for more than one item in the column, you can use the Custom option in the dropdown list to do this.
