# Section without enumeration

I declare sections without numbering by typing section *, but a number is displayed according to the level, as shown in the figure. I want sections declared with section * to have no number here is the current code.

\documentclass[svgnames,french,english,12pt]{report}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage[T1]{fontenc}
\usepackage{anysize}
\marginsize{22mm}{14mm}{12mm}{25mm}
\usepackage{colortbl}
\usepackage{fancybox}
\usepackage[explicit]{titlesec}
\titleformat{\section}[block]{\sffamily\Large\bfseries\color{white}}%
{}{0em}{\colorbox{RoyalBlue!90}{\parbox{\dimexpr\linewidth-2\fboxsep}{\thesection\enspace #1}}}

\titleformat{\subsection}[block]{\sffamily\Large\bfseries\color{white}}%
{}{0em}{\colorbox{RoyalBlue!30}{\parbox{\dimexpr\linewidth-2\fboxsep}{\thesubsection\enspace #1}}}

\titleformat{\subsubsection}{\sffamily\large\bfseries\color{RoyalBlue}}{\thesubsubsection\enspace #1}{1em}{}[{\color{black}\titlerule[1.5pt]}]
\usepackage{tikz}
\usepackage{kpfonts}
\newcommand*\chapterlabel{}
\titleformat{\chapter}
{\gdef\chapterlabel{}
\normalfont\sffamily\Huge\bfseries\scshape}
{\gdef\chapterlabel{\thechapter\ }}{0pt}
{\begin{tikzpicture}[remember picture,overlay]
\node[yshift=-3cm] at (current page.north west)
{\begin{tikzpicture}[remember picture, overlay]
\draw[fill=black] (0,0) rectangle
(\paperwidth,3cm);
\node[anchor=east,xshift=.9\paperwidth,rectangle,
rounded corners=20pt,inner sep=11pt,
fill=MidnightBlue]
{\color{white}\chapterlabel#1};
\end{tikzpicture}
};
\end{tikzpicture}
}
\titlespacing*{\chapter}{0pt}{50pt}{-60pt}
\begin{document}
\chapter{Chapitre 1}
\section*{section without numerotation }
\section{section 1}
\section{section 2}
\section{section without numerotation''}
\end{document}


And this what i get when generate a pdf file .

Thank you for your help !

• In some way off topic. But I think that you have a misconception about \section{...} and \section*{...}. The latter isn't simply a section without numbering. It's more correct to say that it is a section that doesn't increment the counter of sections. Of course, usually you display a \section*{...} but if what you really want is to don't display numbering you should follow other ways. – gvgramazio Jun 8 '18 at 12:27

\titleformat{name=\section, numberless}[block]{\sffamily\Large\bfseries\color{white}}%
