ModernCV modifying the header - Contents in the next line

Question

As a continuation of this question moderncv banking style: How to move the title block all the way to the left?, I would like to bring in the contents, one in each line like :
street and number
city -postcode
country
ph no 1
ph no 2
email
web page

The bullet points are to be removed. the code is:

Answer 1

Just use some extra

\flushmaketitle\@firstmaketitleelementtrue\\        %%% <--- HK here

at appropriate places:

\documentclass[11pt,a4paper,sans]{moderncv}
\moderncvstyle{banking}
\moderncvcolor{blue}

  \setlength{\maketitlewidth}{\textwidth}% NEW
  %\hfil% ORIGINAL

Answer to the comment:

You can use additional parboxes:

\makeatletter
%\renewcommand*{\maketitlesymbol}{}%
%
\renewcommand*{\flushmaketitle}{%
  \strut\usebox{\maketitlebox}%
  \savebox{\maketitlebox}{}%
  \savebox{\maketitletempbox}{}%
  \setlength{\maketitleboxwidth}{0pt}}
\renewcommand*{\maketitle}{%
%  \setlength{\maketitlewidth}{0.8\textwidth}% ORIGINAL
  \setlength{\maketitlewidth}{\textwidth}% NEW
  %\hfil% ORIGINAL
  \parbox{\maketitlewidth}{%
%    \centering% ORIGINAL
    \raggedright% NEW
    % name and title
    \namestyle{\@firstname~\@lastname}%
    \ifthenelse{\equal{\@title}{}}{}{\titlestyle{~|~\@title}}\\% \isundefined doesn't work on \@title, as LaTeX itself defines \@title (before it possibly gets redefined by \title)
    % detailed information
    \addressfont\color{color2}%
    \parbox[t]{0.45\maketitlewidth}{%
    \ifthenelse{\isundefined{\@addressstreet}}{}{\addtomaketitle{\addresssymbol\@addressstreet}%
    \flushmaketitle\@firstmaketitleelementtrue\\       %%% <--- HK here
      \ifthenelse{\equal{\@addresscity}{}}{}{\addtomaketitle[~--~]{\@addresscity}}% if \addresstreet is defined, \addresscity and \addresscountry will always be defined but could be empty
      \flushmaketitle\@firstmaketitleelementtrue\\     %%% <--- HK here
      \ifthenelse{\equal{\@addresscountry}{}}{}{\addtomaketitle[~--~]{\@addresscountry}}%
  \flushmaketitle\@firstmaketitleelementtrue\\     %%% <--- HK here
      }}%
      \hfill
    \parbox[t]{0.45\maketitlewidth}{%
    \raggedleft%    %% optional  
    \collectionloop{phones}{% the key holds the phone type (=symbol command prefix), the item holds the number
      \addtomaketitle{\csname\collectionloopkey phonesymbol\endcsname\collectionloopitem}
      \flushmaketitle\@firstmaketitleelementtrue\\}%           %% <--- HK here
    \ifthenelse{\isundefined{\@email}}{}{\addtomaketitle{\emailsymbol\emaillink{\@email}}}%

\makeatother

Answer 2

The following is a simplified version of \maketitle that avoid adding contents to a box and only setting it at the end. Instead, the contents is set sequentially as it is inspected. I think it makes for code that is a little (shorter and) easier to understand/modify:

\documentclass[12pt,letterpaper]{moderncv}
\moderncvstyle{banking}
\moderncvcolor{blue}
\usepackage{libertine}
\usepackage[scale=0.75]{geometry}

\makeatletter
\renewcommand*{\maketitle}{%
  \setlength{\maketitlewidth}{\textwidth}%
  \parbox{\maketitlewidth}{%
    \raggedright% NEW
    \namestyle{\@firstname~\@lastname}% name and title
    \\% \isundefined doesn't work on \@title, as LaTeX itself defines \@title (before it possibly gets redefined by \title)
    % detailed information
    \addressfont\color{color2}%
    \begin{tabular}{@{}p{\linewidth}@{}}
      \ifthenelse{\isundefined{\@addressstreet}}{}{\addresssymbol\@addressstreet \par}%
      \ifthenelse{\equal{\@addresscity}{}}{}{\@addresscity \par}% if \addresstreet is defined, \addresscity and \addresscountry will always be defined but could be empty
      \ifthenelse{\equal{\@addresscountry}{}}{}{\@addresscountry \par}%
      \collectionloop{phones}{% the key holds the phone type (=symbol command prefix), the item holds the number
        \csname\collectionloopkey phonesymbol\endcsname\collectionloopitem \endgraf}%
      \ifthenelse{\isundefined{\@email}}{}{\emailsymbol\emaillink{\@email} \par}%
      \ifthenelse{\isundefined{\@homepage}}{}{\homepagesymbol\httplink{\@homepage}}%
    \end{tabular}}\\[2.5em]}% need to force a \par after this to avoid weird spacing bug at the first section if no blank line is left after \maketitle
\makeatother

The following version of \maketitle provides a left-and-right alignment of the details:

\makeatletter
\renewcommand*{\maketitle}{%
  \setlength{\maketitlewidth}{\textwidth}%
  \parbox{\maketitlewidth}{%
    \raggedright% NEW
    \namestyle{\@firstname~\@lastname}% name and title
    \\% \isundefined doesn't work on \@title, as LaTeX itself defines \@title (before it possibly gets redefined by \title)
    % detailed information
    \addressfont\color{color2}%
    \begin{tabular}{@{}p{.5\linewidth}@{}p{.5\linewidth}@{}}
      \ifthenelse{\isundefined{\@addressstreet}}{}{\addresssymbol\@addressstreet \par}%
      \ifthenelse{\equal{\@addresscity}{}}{}{\@addresscity \par}% if \addresstreet is defined, \addresscity and \addresscountry will always be defined but could be empty
      \ifthenelse{\equal{\@addresscountry}{}}{}{\@addresscountry} &%
      \raggedleft% For right-aligned content
      \collectionloop{phones}{% the key holds the phone type (=symbol command prefix), the item holds the number
        \csname\collectionloopkey phonesymbol\endcsname\collectionloopitem \endgraf}%
      \ifthenelse{\isundefined{\@email}}{}{\emailsymbol\emaillink{\@email} \par}%
      \ifthenelse{\isundefined{\@homepage}}{}{\homepagesymbol\httplink{\@homepage}}%
    \end{tabular}}\\[2.5em]}% need to force a \par after this to avoid weird spacing bug at the first section if no blank line is left after \maketitle
