Move subsection to next page if its own floats subsection do not fit on the page

Question

I am trying to move a subsection to the next page if the complete subsection (title, the text and the floats) do not fit on the same page.

I don't want the figure to appear before the text.

I tried multiple approaches but I don't even get it to work in this simple example.

• minipage to group the complete subsection
• Using filbreak before subsection
• rewriting subsection command with obscure stuff I did not understand

So what is a working way to do it and what is a recommended way to do it?

EDIT: To be more clear. I want Subsection 2 moved to the next page, so that it is on the same page as the figures which belong into it. Because they fit on one page, they should be on one page.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\usepackage{graphicx}
\usepackage{etoolbox}
\usepackage{subcaption}

\title{SubsectionFloats}
\date{December 2022}

\begin{document}

\maketitle

\section{Introduction}
\subsection{Subsection 1}
\lipsum[2]
%\newpage ---------------   Here a new page should begin since subsection does fit on a single page but would be split by a pagebreak between text and figure if no newpage command is used. 
\subsection{Subsection 2}
\lipsum[5]
\begin{figure}
\begin{subfigure}{\textwidth}
    \centering
    \includegraphics[scale=0.5]{example-image-c}
    \caption{Caption1}
    \label{fig:my_label}
\end{subfigure}
\begin{subfigure}{\textwidth}
    \centering
    \includegraphics[scale=0.5]{example-image-c}
    \caption{Caption2}
    \label{fig:my_label2}
\end{subfigure}
\centering
\caption{Figures}
\end{figure}

\end{document}

Answer 1

I don't really understand what you want. You say if a subsection is too long then move it to the next page. But on the next page it will be too long so move to the next page, and so on and so on. Just manually use \newpage where you want it.
