How to display values in multiple lines if multiple checkbox's are selected?

In my userform I have a list of check box's that can be selected. Currently if more than one is selected, they will appear in the spread sheet in the same line one after another with a space between them. How do I make it so they either appear with a comma appearing after each, or so the next value appears on the next line below?

Current code

If CheckBox1.Value = True Then ws.Cells(iRow, 2).Value = ws.Cells(iRow, 2).Value & " " & CheckBox1.Caption
If CheckBox2.Value = True Then ws.Cells(iRow, 2).Value = ws.Cells(iRow, 2).Value & " " & CheckBox2.Caption
If CheckBox3.Value = True Then ws.Cells(iRow, 2).Value = ws.Cells(iRow, 2).Value & " " & CheckBox3.Caption
If CheckBox4.Value = True Then ws.Cells(iRow, 2).Value = ws.Cells(iRow, 2).Value & " " & CheckBox4.Caption
If CheckBox5.Value = True Then ws.Cells(iRow, 2).Value = ws.Cells(iRow, 2).Value & " " & CheckBox5.Caption
If CheckBox6.Value = True Then ws.Cells(iRow, 2).Value = ws.Cells(iRow, 2).Value & " " & CheckBox6.Caption
