At a client's office last week, I was selecting a pricing option from a data validation drop down list. The worksheet was zoomed to 75%, so we could see more of the data, and the person watching over my shoulder asked, "How can you even read that?"
Good question. Sometimes the font in a data validation drop down is so small that you can barely read the list.
Unfortunately, there's no way to make the font size bigger, which is one of the drawbacks of a data validation drop down list. There are other ways to create a drop down list though, and one of those options might work better in your worksheet.
We'll compare these types of Excel drop down lists:
- Data Validation List
- Form Control Combo Box
- ActiveX Control Combo Box
Data Validation List
Data validation is a great feature, and you can use creative formulas to create flexible lists, such as dependent drop down lists. However, the font size can't be changed, only 8 rows are visible at a time, and only the active cell shows a drop down arrow.
You can't change those settings, but you can colour the data entry cells, to make them obvious to the worksheet users.
Form Control Combo Box
Instead of using data validation, you could use a Form Control Combo Box. It gives you a bit more control over the appearance of the drop down list.
You can adjust the number of drop down lines in the Form Control Combo box, so you can show all 12 months, without a scroll bar.
The drop down arrow is always visible, to the Form Control combo box is easy for users to find on the worksheet. The font size can't be changed though, so the list would be hard to read on a zoomed worksheet.
If you select an item from the Form Control drop down list, the item number is entered in the linked cell. In the screen shot below, February was selected, and a 2 is entered in cell D5.
To show the item name, instead of the item number, you can use an INDEX function in another cell. In this example, the INDEX function returns a month name from the MonthList named range, from the row number (2) for the selected month (February).
ActiveX Combo Box
Another drop down list option is to use an ActiveX combo box. This is similar to the Forms Control combo box, but has more properties that you can adjust.
After you insert a combo box, right-click the combo box, and click Properties.
You can set the properties, such as font, font size, number of rows, and even include multiple columns.
If you know that a worksheet will be zoomed most of the time, you can use a larger font, to make the list easier to read.
Combine the Drop Down Lists
To make the most of the data validation features, while allowing font changes, autocomplete and more rows, I sometimes combine data validation with a combo box. There's only one combo box, hidden at the top of the worksheet, and bit of programming makes the combo box appear when needed.
When a user double-clicks on a data validation cell, the combo box appears, and displays the data validation list for the selected cell. If users don't want to use the combo box, they can simply click on the arrow in the cell, and use the data validation list.
