Overcome the limitation of a drop down list by using a combo box, that refers to named ranges which contain the list items.
NOTE: You can't use ActiveX controls on a Macintosh. Prof. Lee Townsend shows how to create drop downs using Form control combo boxes.
You can use Data Validation to create a dropdown list of options in a cell. However, the list font can't be changed, nor can the number of visible rows, which has a maximum of eight. Also, Data Validation doesn't have an AutoComplete feature, which finds matching items in the list as you start to type.
To overcome these limitations, you can add a combo box to your worksheet, and use programming to make it appear in cells that contain a data validation list.
Double-click on a cell that contains a data validation list, and the combo box appears. The combo box's font size can be set, more than 8 rows can be displayed, and autocomplete can be enabled.
Note: If the worksheet is protected, allow users to Edit Objects, and they will be able to use the combobox.
To see how the combo box works, and appears when you double-click a data validation cell, watch this short video.
Two worksheets are required in this workbook.
IMPORTANT: Set the ValidationLists sheet at 100% zoom, to avoid crashing Excel. There is a strange bug connected to combo boxes and zoom levels.
You can adjust the zoom level on the ValidationSample sheet, but do not change ValidationLists from 100%.
On the ValidationLists sheet, type the lists that will be used in the data validation dropdowns:
Tip: Use the AutoFill feature to create the lists
Name the lists (there are Naming instructions here: Name a Range):
The next step is to create the dropdown lists. There are detailed instructions here: Excel Data Validation Introduction
To add or edit the Combobox, follow these steps:
To format the combo box, open the properties window:
Visual Basic for Applications (VBA) code is required to make the combo box appear when you double-click in a cell that contains a data validation list. See details in the next section, for How the Code Works.
Copy the following code
'========================== Private Sub Worksheet_BeforeDoubleClick _ (ByVal Target As Range, _ Cancel As Boolean) Dim str As String Dim cboTemp As OLEObject Dim ws As Worksheet Set ws = ActiveSheet Set cboTemp = ws.OLEObjects("TempCombo") On Error Resume Next With cboTemp 'clear and hide the combo box .ListFillRange = "" .LinkedCell = "" .Visible = False End With On Error GoTo errHandler If Target.Validation.Type = 3 Then 'if the cell contains 'a data validation list Cancel = True Application.EnableEvents = False 'get the data validation formula str = Target.Validation.Formula1 str = Right(str, Len(str) - 1) With cboTemp 'show the combobox with the list .Visible = True .Left = Target.Left .Top = Target.Top .Width = Target.Width + 5 .Height = Target.Height + 5 .ListFillRange = str .LinkedCell = Target.Address End With cboTemp.Activate 'open the drop down list automatically Me.TempCombo.DropDown End If errHandler: Application.EnableEvents = True Exit Sub End Sub '========================================= Private Sub TempCombo_LostFocus() With Me.TempCombo .Top = 10 .Left = 10 .Width = 0 .ListFillRange = "" .LinkedCell = "" .Visible = False .Value = "" End With End Sub
'==================================== 'Optional code to move to next cell 'if Tab or Enter are pressed 'from code by Ted Lanham '***NOTE: if KeyDown causes problems, 'change to KeyUp 'Table with numbers for other keys 'such as Right Arrow (39) 'https://msdn.microsoft.com/en-us/ library/aa243025%28v=vs.60%29.aspx
'For dates or numbers in the data validation, you can use the KeyDown code in the Code for Numbers section below.
Private Sub TempCombo_KeyDown(ByVal _ KeyCode As MSForms.ReturnInteger, _ ByVal Shift As Integer) Select Case KeyCode Case 9 'Tab ActiveCell.Offset(0, 1).Activate Case 13 'Enter ActiveCell.Offset(1, 0).Activate Case Else 'do nothing End Select End Sub '====================================
Here are some details on how the code works.
This code runs when a cell is double-clicked.
Variables are set for the active sheet, and the combo box named TempCombo -- be sure to use that name for your combo box.
Set ws = ActiveSheet Set cboTemp = ws.OLEObjects("TempCombo")
The combo box is hidden, and its linked cell and ListFillRange are cleared.
With cboTemp 'clear and hide the combo box .ListFillRange = "" .LinkedCell = "" .Visible = False End With
The data validation type for the Target cell (the active cell) is checked. If it is Type 3 (a drop down list), the rest of the code runs.
If Target.Validation.Type = 3 Then
The str variable gets the data validation formula for the Target cell. For example: "=MonthList". Then, the equal sign is removed, by using the Right function. That leaves just the Range name for the data validation list -- "MonthList"
str = Target.Validation.Formula1 str = Right(str, Len(str) - 1)
The combo box is made visible, an is positioned at the top left of the Target cell
With cboTemp 'show the combobox with the list .Visible = True .Left = Target.Left .Top = Target.Top
The combo box width and height are determined by the Target cell's width and height, with a small amount added. You can change the "+5" to a different number:
.Width = Target.Width + 5
.Height = Target.Height + 5
The ListFillRange is changed to the str variable -- MonthList -- so the combo box will show the items from that named range.
.ListFillRange = str
The LinkedCell is changed to the Target cell's address.
.LinkedCell = Target.Address
The combo box is activated, and the drop down list is opened.
cboTemp.Activate Me.TempCombo.DropDown End If
This code runs when you exit the combo box
The combo box is hidden, moved to the top left of the worksheet, and its linked cell and ListFillRange are cleared.
With Me.TempCombo .Top = 10 .Left = 10 .Width = 0 .ListFillRange = "" .LinkedCell = "" .Visible = False .Value = "" End With
IMPORTANT: Leave the ValidationLists sheet at 100% zoom, to avoid crashing Excel. There is a strange bug connected to combo boxes and zoom levels.
If you decide to change the combo box properties later, it might be difficult to find the combo box on the worksheet, because the code changes its width to zero.
Follow these steps to locate the combo box, and adjust its properties:
NOTE: The combo box width and height are set in the macro -- changing these values in the property window will not have a long term effect. Edit the code, if you want the size to change.
The values that you select in a combo box are treated as text, so that can cause problems if your drop down list contains numbers (including dates and times). In the screen shot below, a time has been selected, and even though the cell is formatted for Time, it appears in the cell as a long decimal number. The entry is really text, not a number, so the number formatting does not affect it.
To send the numbers to the worksheet as real numbers, instead of text, use the following code, instead of the TempCombo_KeyDown code above.
Then, after you select a number (or date or time) in the combo box drop down list, press the Enter key or the Tab key, to move to the next cell.
NOTE: This code is used in the sample file, that you can download below. You can test it in column D on the Validation Sample sheet.
'==================================== 'Optional code to move to next cell 'if Tab or Enter are pressed 'from code by Ted Lanham '***NOTE: if KeyDown causes problems, 'change to KeyUp Private Sub TempCombo_KeyDown(ByVal _ KeyCode As MSForms.ReturnInteger, _ ByVal Shift As Integer) 'move to next cell on Enter and Tab Dim varVal As Variant On Error Resume Next 'change text value to number, if possible varVal = --ActiveCell.Value If IsEmpty(varVal) Then varVal = ActiveCell.Value End If Select Case KeyCode Case 9 'tab ActiveCell.Value = varVal ActiveCell.Offset(0, 1).Activate Case 13 'enter ActiveCell.Value = varVal ActiveCell.Offset(1, 0).Activate Case Else 'do nothing End Select End Sub '====================================
There is a premium version of this technique, and you can see the details here: Data Validation Multi Select Premium. It runs on a protected worksheet, and works with most dependent drop down lists.
In the premium version, a list box automatically appears when you select a cell that has a drop down list. You can set it to allow selection of a single item (button), or multiple items.
For multiple selections, the listbox pre-selects any items that are already in the cell. It also has buttons to Clear all the selections, and select all the items.
The kit has a setup sheet, that lets you quickly customize the listbox, and details on how to add this technique to your own workbooks. See the details here: Data Validation Multi Select Premium.
To test the combo box code, you can download the zipped sample file.
