N.J. Stat. § 19:14-9
A candidate who receives more than one nomination for the same office, either from more than one political party or from more than one group of petitioners, or from one or more political parties and one or more groups of petitioners, shall have his name printed on the official general election ballot in only one column to be selected by him from among the columns to which his nominations entitle him, and shall have such designations after his name as he shall select, consisting of the names of the political parties nominating him, with the words "Indorsed By", if he so desires, and the several designations to which he is entitled by the other nominations, if any, and printed in such order as he shall select.
The candidate shall file with the secretary of state or county clerk, as the case may be, his selection of his column, and the designations to follow his name and their order. Unless such selection is so filed within seven days after the primary election, the secretary of state or county clerk, as the case may be, shall determine in what column and with what designations his name shall be printed. The designations shall be printed in small type, and if necessary, in several lines or in a line below his name and may be abbreviated.
