Clearing data in a cell but not the formatting
I have a spreadsheet with a column of entries that are formatted as a pop-up menu. What I am trying to do is clear the data values, but not delete the pop-up formatting. I can't find a way to do that. If I select the column and hit the delete key, the data disappears as expected, but so does the pop-up menu. If I use the edit menu and select either "Delete" or "Clear", the same thing happens. Is there any way that I can delete the data from these cells, without losing the pop-up menu?
