Child Numbers: Items follow section numbers

Question

I'd like the numbering of items in the document to reflect the numbers of the sections in which they are found. In the MWE, the numbering is

Section 1

1.

2.

Section 2

1.

2.

What I want is:

Section 1

1.1

1.2

Section 2

2.1

2.2

How can I achieve this?

\documentclass[11pt]{article}
 
\begin{document}
%\maketitle
%\section{}
%\subsection{}

\section{Structure}
\begin{enumerate}

\item
first point
\item
Second point

\end{enumerate}

\section{Circus Tents}
\begin{enumerate}
\item
number
\item
kind
\end{enumerate}



\end{document}  

Answer 1

There are a number of ways to achieve this. First, if you're not into using packages, adjust \labelenumi by adding this to your document preamble: \renewcommand\labelenumi{\thesection.\theenumi.}. It prefixes \thesection to the default label.

\documentclass{article}

\renewcommand\labelenumi{\thesection.\theenumi.}

\begin{document}

\section{Structure}

\begin{enumerate}
  \item
  First point

  \item
  Second point
\end{enumerate}

\section{Circus Tents}

\begin{enumerate}
  \item
  Number

  \item
  Kind
\end{enumerate}

\end{document}

This process is made a little more easy using enumitem:

\documentclass{article}

\usepackage{enumitem}
\setlist[enumerate,1]{label=\thesection.\arabic*.}

\begin{document}

\section{Structure}

\begin{enumerate}
  \item
  First point

  \item
  Second point
\end{enumerate}

\section{Circus Tents}

\begin{enumerate}
  \item
  Number

  \item
  Kind
\end{enumerate}

\end{document}
