# How to make (an equivalent) of \vfill work on a breakable page spanning tcolorbox?

This is a follow up question to: How to make a breakable tcolorbox which spans the total text height?

I want to add some text on the bottom of the last page inside of the colorbox. But \vfill doesn't work. Any ideas?

\documentclass{article}

\usepackage[breakable]{tcolorbox}
\usepackage[top=2cm,bottom=2cm,hmargin=2.2cm]{geometry}

\usepackage{lipsum}

\begin{document}

\begin{tcolorbox}[breakable,height fixed for=all]
\lipsum[1-10]

\vfill

Some text on the bottom of the last page.
\end{tcolorbox}

\end{document}


\vfill can't work. But you can cheat and add an overlay (the shift values aren't correct yet). Be aware that if your box is full, the overlay can overwrite the text.

\documentclass{article}

\usepackage[breakable,most]{tcolorbox}
\usepackage[top=2cm,bottom=2cm,hmargin=2.2cm]{geometry}

\usepackage{lipsum}

\begin{document}

\begin{tcolorbox}[breakable,height fixed for=all,enhanced,
overlay last={\node[anchor=base west] at ([xshift=1cm,yshift=1cm]frame.south west){Some text on the bottom};}]
\lipsum[1-10]

\end{tcolorbox}

\end{document}
