How can i edit a template?

Question

I found this template https://es.overleaf.com/latex/templates/wiley-journal-template/nnjcnfyhzcqp and I want to hide the Correspondence, Present address and Funding information. For example when I delete the \fundinginfo command it only removes the text, but not the Funding information title.

Answer 1

You can modify the class file that's in the template. Namely,use \ifdefempty to check whether the Funding information is empty.

Take these lines (477-479 in wiley-article.cls):

  \vskip10pt%
  \textbf{Funding information}\\
  \@fundinginfo\par

and change them to this:

  \ifx\empty\@fundinginfo
  \else
    \vskip10pt
    \textbf{Funding information}\\
    \@fundinginfo\par
  \fi

Then if you invoke \fundinginfo{} in the preamble, things should work properly. You can do similar modifications to the other fields.
