Use Checkboxes to Filter a List

I am working on a tool and need to accomplish several things using the checkbox form control. I have a questionnare that needs to be filtered by functional role so that the appropriate person can complete the appropriate questions and not have to view the entire list.

I have assigned roles to each question by entering IT, HR, FM, or PS in the next column. I can use autofilter to show just the questions for each role or multiple roles but I want the form to be easy for the user so checkboxes would be a better solution. The checkboxes should allow the user to select one or multiple roles. Additionally, the user should be able to uncheck a role checkbox to hide the associated questions if he/she makes an error in selecting his/her role.

Please help. I have very little knowledge of VBA script.

Here is a simple version of my questionnare.
Sample for forum.xlsm

Thank you for the code! I was however, I was able to get the following code to work when I assigned the checkboxes to column CK for "true" and "false" value to populate.

Sub IT_Click()
Dim searchcriteria As String
Dim i As Integer
' reading what has been clicked, line below reads the value from row 1 and column 91
If Worksheets("Input- Questions").Cells(1, 91).Value = True Then
'If ActiveSheet.Shapes("IT").Value = xlOn Then
For i = 12 To 178
If Range("CK" & i).Value = "IT" Then
ActiveSheet.Rows(i).Hidden = False

End If
Next
End If
If Worksheets("Input- Questions").Cells(1, 91).Value = False Then
'If ActiveSheet.Shapes("IT").Value = xlOn Then
For i = 12 To 178
If Range("CK" & i).Value = "IT" Then
ActiveSheet.Rows(i).Hidden = True

End If
Next
End If
End Sub
