You will need a couple of macros for this.
Looking at your illustration suggests that the list has a title "Quality 2015", and that all the entries begin with 9001. (If there are other sequences you will need to modify the macro to address them)
The following macro will split that list to show only the numbers while retaining the value as the full texts shown:
Code:
Sub Macro1()
Dim oCC As ContentControl
Dim i As Integer
Dim strValue As String, strText As String
Dim Coll As Collection
Set oCC = ActiveDocument.SelectContentControlsByTitle("Quality 2015").Item(1)
Set Coll = New Collection
With oCC.DropdownListEntries
For i = 1 To .Count
strValue = .Item(i).Text
strText = onlyDigits(.Item(i).Text)
strText = Replace(strText, "9001", "9001 ")
Coll.Add strText & "|" & strValue
Next i
.Clear
.Add "Choose an item", ""
For i = 1 To Coll.Count
.Add Split(Coll.Item(i), "|")(0), Split(Coll.Item(i), "|")(1)
Next i
End With
End Sub
Private Function onlyDigits(s As String) As String
Dim retval As String
Dim i As Integer
retval = ""
For i = 1 To Len(s)
If Mid(s, i, 1) >= "0" And Mid(s, i, 1) <= "9" _
Or Mid(s, i, 1) = "." Then
retval = retval + Mid(s, i, 1)
End If
Next
onlyDigits = retval
End Function
Run the macro to modify the list.
Then add the following macro to the ThisDocument module of the document:
Code:
Option Explicit
Private Sub Document_ContentControlOnExit(ByVal CC As ContentControl, Cancel As Boolean)
Dim lngIndex As Long
Dim strValue As String
Select Case CC.Title
Case "Quality 2015"
If CC.ShowingPlaceholderText Then GoTo lbl_Exit
With CC
For lngIndex = 2 To .DropdownListEntries.Count
If .DropdownListEntries(lngIndex).Text = .Range.Text Then
strValue = .DropdownListEntries(lngIndex).Value
.Type = wdContentControlText
.Range.Text = strValue
.Type = wdContentControlDropdownList
Exit For
End If
Next lngIndex
End With
Case Else
End Select
lbl_Exit:
Exit Sub
End Sub
Select a number, then click outside the control to display the value. See attached mock-up
