Appendices does not work well in a table of contents for the elsarticle class.


\section{Extra material}

"Appendix A" and "Extra material" are typeset on top of each other in the table of contents. Are there any fixes to this problem?


You can fix it by redefining \thesection after \appendix, i.e.


Now you would get "A. Extra material". Originally, elsarticle defines within \appendix:


which results in "Appendix A Extra material". The section number is typeset using \numberline which doesn't fit.

Alternatively you could just set in your preamble


I think, if you don't write "Section 1" and "Section 2", there's no need to write "Appendix A" and "Appendix B". Firstly, for consistency in naming, secondly because alphabetic numbering already signalizes appendices.
