\arguments{
\item{page_size}{page dimensions, an object generated with function \link{page_size}.}

\item{page_margins}{page margins, an object generated with function \link{page_mar}.
It is recommended to use the same margins object across all sections to prevent
unintended page breaks.}

\item{type}{Section type. It defines how the contents of the section will be
placed relative to the previous section. Available types are "continuous"
(begins the section on the next paragraph), "evenPage" (begins on the next
even-numbered page), "nextColumn" (begins on the next column on the page),
"nextPage" (begins on the following page), "oddPage" (begins on the next
odd-numbered page).}

\item{section_columns}{section columns, an object generated with function
\link{section_columns}. Use NULL (default value) for no content.}

\item{header_default}{content as a \code{\link[=block_list]{block_list()}} for the default page header.
Use NULL (default value) for no content.}

\item{header_even}{content as a \code{\link[=block_list]{block_list()}} for the even page header.
Use NULL (default value) for no content.}

\item{header_first}{content as a \code{\link[=block_list]{block_list()}} for the first page header.
Use NULL (default value) for no content.}

\item{footer_default}{content as a \code{\link[=block_list]{block_list()}} for the default page footer.
Use NULL (default value) for no content.}

\item{footer_even}{content as a \code{\link[=block_list]{block_list()}} for the even page footer. Use
NULL (default value) for no content.}

\item{footer_first}{content as a \code{\link[=block_list]{block_list()}} for the default page footer.
Use NULL (default value) for no content.}

\description{
A section is a grouping of blocks (ie. paragraphs and tables)
that have a set of properties that define pages on which the text will appear.

A Section properties object stores information about page composition,
such as page size, page orientation, borders and margins.

\strong{Important}: When creating multiple sections in a document, it is strongly
recommended to use the \strong{same \code{page_margins} object} for all sections to avoid
unwanted page breaks. Changing page margins between sections can cause Word to
insert automatic page breaks, even when using \code{type = "continuous"}. To ensure
consistent behavior, create a single \code{page_mar()} object and reuse it across
all \code{prop_section()} calls. See the examples in \code{\link[=body_end_block_section]{body_end_block_section()}} which
demonstrate this best practice.

# Example 1: Mixing different section layouts ----
# This example demonstrates how to create a document with multiple sections,
# each with different page orientations and column layouts

# Define a landscape section with single column
# This is useful for wide tables or charts

# - Different header/footer for even pages (left-side pages in duplex printing)
# - Default header/footer for odd pages (right-side pages)
