# Disable hyphenation in ToC

I am using classicthesis and arsclassica to write some book. In order to prevent hyphenation in section title, I added

\titleformat{\section}
{\raggedright}{\textsc{\MakeTextLowercase{\thesection}}}{1em}{\spacedlowsmallcaps}


which I got from here. Consider this MWE.

\documentclass[b5paper,12pt,twoside]{book}
\usepackage[pdfspacing]{classicthesis}
\usepackage{arsclassica}
\usepackage[inner=2.2cm,outer=1.8cm,bottom=2.7cm,top=2.5cm]{geometry}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\usepackage[english]{babel}

\titleformat{\section}
{\raggedright}{\textsc{\MakeTextLowercase{\thesection}}}{1em}{\spacedlowsmallcaps}

\begin{document}
\frontmatter
\tableofcontents
\cleardoublepage
\mainmatter
\chapter{Test Chapter}
\section{The Separation Axioms and Continuous Real-Valued Functions}
\lipsum
\end{document}


It worked for the section title, but I still get hyphenation in ToC. How to disable hyphenation in ToC as well?

• If you want to disable hyphenation for all entries in ToC, LoF and LoT: \makeatletter\renewcommand{\@tocrmarg}{2.55em plus1fil}\makeatother – esdd May 5 '18 at 18:34
