table of contents
I am using example given here by @stephan TOC Section & Subsection coloring.
Works great however I want to get rid of dots and page numbers.
I added this to the preamble
\let\Contentsline\contentsline
\renewcommand\contentsline[3]{\Contentsline{#1}{#2}{}}
that removed the page numbers, but do not know how to remove the dots. I would appreciate your help. Its hard to get result without understanding the basics.
A heading command like \section{A} writes a line into the .toc file that looks like this:
\contentsline {section}{\numberline {1.1}A}{2}
when this is read back in \contentsline{section} simply expands to \l@section and that is then the command that picks up the remaining arguments and produces the toc entry. Most often (but not always) this command is defined as a special instance of \@dottedcontentsline, e.g., in the book class you find:
\newcommand*\l@section{\@dottedtocline{1}{1.5em}{2.3em}}
So to get rid of the dots in some cases there are different approaches possible and the depend on how things are defined and which entries you have to change in reality.
Assuming that your toc uses \@dottedtoclinethen to get rid of the dots we can redefine \@dotsep to have a very high number. Assuming further, that we only want to change the sections at the end of the toc and we do not need to have dots appearing later on again. Then the following in front of the appendix in the source document will do the trick:
\makeatletter
\addtocontents{toc}{\def\string\@dotsep{100}}
\makeatother
This will write \def\@dotsep{100} into the toc file and from that point on the dots are gone.
If you need them back at a later point issue
\makeatletter
\addtocontents{toc}{\def\string\@dotsep{4.5}} % 4.5 might be a different value in your class
\makeatother
Make the heading commands in the appendix area or whenever you want a different toc style not write \contentsline{section}but, say, \contentsline{appsection} and then define \l@appsection to format the toc entry according to the desired style.
For this one would need to look for the places in the heading commands that issue \addcontentsline and change that code.
Fairly elaborate but much more general.
If you want all \subsections to be removed from the ToC, then all you need in your document preamble is
\setcounter{tocdepth}{1}
which would set the maximum depth of entries in the ToC to 1 (or \section).
If you only want selected \subsections to be inserted/not in the ToC, then you should use a different technique. The following defines \stoptocentries and \starttocentries. The former disables inserting content in the ToC by disabling \addcontentsline. The latter restores the functionality.
\documentclass{article}
\let\oldaddcontentsline\addcontentsline
\newcommand{\stoptocentries}{\renewcommand{\addcontentsline}[3]{}}
\newcommand{\starttocentries}{\let\addcontentsline\oldaddcontentsline}
\begin{document}
\tableofcontents
\section{A section}
\stoptocentries% Stop adding content to the ToC
\subsection{A subsection}
\starttocentries% Resume adding content to the ToC
\subsection{Another subsection}
\end{document}
Of course, usage of \stoptocentries also pertains to other sectional units that use \addcontentsline.

Method - 1: Add
in your preamble.
Method - 2: This can be achieved by
tocloftpackage also. Here one has to useto remove the page numbers and
to remove the dots.
