I am attempting to implement the following formatting:
I have done my best to adapt it into the following:
\documentclass{article}
\usepackage{titlesec} % section headings
\usepackage{enumitem} % customize lists
\setcounter{secnumdepth}{0} % disable section auto-enumerating
\titleformat{\subsection}[wrap]{\normalfont}{}{}{}
\titlespacing{\subsection}{2pc}{1pc}{2pc}
\begin{document}
\section{Chapter 5}
\subsection{5.1}
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras eget malesuada mi, nec feugiat lacus. Nullam est mi, feugiat eu congue ut, ultricies sed nulla. Cras sed eros id odio lobortis viverra a a est. Nulla facilisi. Duis a metus sit amet sapien accumsan egestas. Quisque dignissim magna eros, a auctor lectus sollicitudin ultrices.
\begin{enumerate}[label={\alph*.}]
\item Donec sit amet nulla velit. Nulla facilisi. Aenean placerat, metus dapibus hendrerit tincidunt, diam sem ultricies sapien, nec ultricies diam odio eu ligula. Praesent non eros posuere, tristique turpis dapibus, fermentum tortor. Nam tempus tristique ex ac fermentum?
Answer content (a)
\item Duis vitae congue felis. Cras sollicitudin facilisis enim. Phasellus rhoncus libero ultrices turpis semper, id ornare quam cursus. Praesent sed aliquet tortor. Cras nec blandit sapien?
Answer content (b)
\end{enumerate}
\end{document}
This renders as:
A critical piece that I am failing to adapt is the un-indentation of the Answer contents (a) & (b). What is the best way to go about formatting these un-indented sub-elements of the list, without breaking from the {enumeration} environment?
Thanks! (This question was adapted based on responses from Willie Wong, Werner♦, and barbara beeton to a previous question.)



\leftskip-\leftmargin. But it would be better if you edit your document to show a more realistic use case. In particular, in your use case, (I) do you expect the "Answer content (a)" to be a single paragraph or multiple paragraphs? (II) is the code supposed to print "Answer content (a)" automatically, or is that just a place holder? Depending on your needs, it is possible https://tex.stackexchange.com/questions/217722/enumitem-indented-list-where-new-paragraphs-are-not-indented already answered your question. – Willie Wong Dec 14 '23 at 04:01\begin{enumerate}[resume*](the starred veresion will here get the formattting from the previous list. – daleif Dec 14 '23 at 10:46
