I met a problem about how to make the long link into a multi-lines one.
The following is LaTeX code:
\documentclass[11pt]{article}
\usepackage[colorlinks,citecolor=black,linkcolor=black]{hyperref}
\PassOptionsToPackage{hyphens}{url}
\begin{document}
\section{example}
test \footnote{photo from:Ferroelectrics-Physical-Effects,M.Lallart,2011,InTech, \\ \url{http://www.intechopen.com/books/ferroelectrics-physical-effects/photo-induced-effect-in-quantum-paraelectric-materials-studied-by-transient-birefringence-measuremen} }:
\end{document}
I referred to the suggestions of this Forcing linebreaks in \url
But I still could not make \url work in sloppypar.
That means when I delete \url{content} only put "content" in sloppypar it will work but I need \url to highlight or distinguish the url link.
How can I realize this?
I use XeLaTeX.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem have been solved. Thank you @Herbert You really give me a lot of help.
I should change the \PassOptionsToPackage{hyphens}{url} to \usepackage[hyphens]{url} and that will works :
I guess I have used the wrong code to Pass Option.


hyperref,urland one word and the footnote – May 23 '13 at 06:45!in front of it to turn it into a link. A moderator or another user with edit privileges can then reinsert the!to turn it into an image again. Herbert was referring complete minimal example which helps answering people a lot. It is advisable not to post code in comments rather insert in Q which can be noticed as well. – texenthusiast May 23 '13 at 06:59
