Hey Brian,
i just learned how to do this - there may be a better or more sophisticated
way but this is what worked for me. I added a new worksheet to the
spreadsheet where I want to use the list and called it "work area". On the
work area worksheet I created my list like this (I needed the drop down to
contain these choices: New, Open, Closed):
A1 blank
A2 New
A3 Open
A4 Closed
Then I selected all four of those cells and entered a name for them in the
name box (top left box above column header A that usually displays the cell
address) - I called my list ValidStatusList.
Next I went to the worksheet and cell where I want to display the list.
Once the cell is selected, go to Data->Validation->Settings.
In the allow box, select "List".
Make sure "In cell dropdown box" is selected.
In the Source box, put =Name (where Name is the name you gave the list
earlier)
Click OK.
If you want to color code the cell based on the choice selected from the
dropdown list, select the cell with the list and use Format->Conditional
Formatting. For my list above, I wanted to draw attention to the items that
were identified as "New" so the condition I set was:
Condition 1 "Cell Value Is" "equal to" ="New"
and then I selected "Format..." and on the Patterns tab I set the color to
purple.
I put the list on a separate worksheet because I actually had several lists
to make and figured I could just hide the worksheet once I was done so that
the users do not see it. I am not sure how else you might store the lists.
