The Page Numbering Style defines the type of page numbering that is used for a Section. The Page Numbering Style setting automatically sets the Page Numbering > Style option in InDesign’s Numbering & Section Options.
To edit the Page Numbering Style for a section, select the preferred numbering style from the Style pop-up menu.
The default style is Arabic. Alternate numbering styles are Arabic with leading zeroes, Roman numerals (i, ii, iii etc.) and Alpha (a, b, c etc.) in lower- and upper-case variants.
