Question

I want to have a sheet with several rows, each with a ‘+’ button. When the button is clicked, a “template” row that is hidden is copy&insert below the row of the button.

Answer 1

Assuming that the hidden row is row 2 and that you only need a single button that will copy row 2 to the row below the active cell:

    Sub CopyRow
       Rows("2:2").Copy Destination:=Cells(ActiveCell.Row + 1, 1)
    End sub
