# labels before entries in only one of two split biographies

I use labels before entries in the bibliography, just as in the solution given in Bibliography styles like authordate2 in biblatex or natbib?, which works like a charm. However, I need to limit the labels to just the first part of the bibliography (being the second dedicated to online sources without author) which I manage with filters as per MWE. I'm using biblatex, biber, APA style, italian. I edit on Sharelatex.com.

\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage[babel]{csquotes}
\usepackage[style=apa,backend=biber]{biblatex}
\DeclareLanguageMapping{italian}{italian-apa}

%LABELS
\defbibenvironment{bibliography}
{\list
{
\printtext[]{%
\begingroup
\defcounter{maxnames}{\value{mymaxcitenames}}%
\printnames{labelname}%
\setunit{\nameyeardelim}%
\printfield{labelyear}%
\printfield{extrayear}%
\endgroup
}%
}
{\setlength{\labelwidth}{100pt}%
\setlength{\leftmargin}{\labelwidth}%
\setlength{\labelsep}{\biblabelsep}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}%
\renewcommand*{\makelabel}[1]{\hfill##1\hss}
}
{\endlist}
{\item}

\defbibfilter{online}{
type=online
}

\defbibfilter{offline}{
type=book or
type=article or
type=report
}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}

@online{cit1,
title = {Title},

That should be as easy as renaming your new bibliography environment to bibwithlabels, say.

\defbibenvironment{bibliography}
{\list
{
\printtext[]{%
\begingroup
\defcounter{maxnames}{\value{mymaxcitenames}}%
\printnames{labelname}%
\setunit{\nameyeardelim}%
\printfield{labelyear}%
\printfield{extrayear}%
\endgroup
}%
}
{\setlength{\labelwidth}{100pt}%
\setlength{\leftmargin}{\labelwidth}%
\setlength{\labelsep}{\biblabelsep}%

and use that for the offline bibliography with the env option
\printbibliography[heading=bibintoc,filter=offline,title={Bibliography},env=bibwithlabels]
