If a municipality has single-member districts for the election of council members when the council-manager form of government is adopted in the municipality, the municipality shall continue with either four or six council members elected from single-member districts and the mayor shall be elected at large. The question on the ballot shall indicate the composition of the mayor and council should the council-manager form of government be adopted. If the adoption of the council-manager form of government is approved as provided in Section 11-43A-6, the municipality shall be governed by this article, except to the extent of any direct conflict in this article concerning the number and election of members of the council as provided in this section.
