Break up \listoftables and \listoffigures by adding section names

Question

Is it possible to use \listoftables and \listoffigures, but to have the lists divided by sections, similar to how the table of contents works?

Answer 1

It's easy to write to the file but you have to get the timing right so the heading comes in the logical place, easiest to put the heading in the first float of each section rather than at the heading.

\documentclass{article}

\usepackage{flafter}

\begin{document}

\listoffigures

\section{Red}


abc
\begin{figure}\addtocontents{lof}{\protect\subsection*{Red}}
\caption{aaa}\end{figure}
abc
\begin{figure}\caption{bbb}\end{figure}

\section{Blue}

abc
\begin{figure}\addtocontents{lof}{\protect\subsection*{Blue}}
\caption{cc}\end{figure}
abc
\begin{figure}\caption{dd}\end{figure}

\end{document}
