Why using itemize cannot bold in third line with $H_{1,1}$

Question

I am trying to bold the word in my third line. as shown in figure below:

My full MWE is as below:

    \documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}

\begin{document}

\renewcommand{\labelitemi}{$\blacksquare$}
\renewcommand{\labelitemii}{$\square$}
\renewcommand{\labelitemiii}{\textendash}
\begin{itemize}
   \item  \textbf{First Line}
   \begin{itemize}
     \item  \textbf{Second Line}
        \begin{itemize}
             \item \textbf{\(H_{1,1}\):} No bold starting here Third Line
                %  \item {\textbf{\(H_{1,2}\):}} There 

\end{itemize}
\end{itemize}
\end{itemize}

\end{document}

I had tried:

 \item \textbf{\(H_{1,1}\):} No bold starting here Third Line

and

\item {\textbf{\(H_{1,2}\):}} There

I have edited the tags, especially to remove biblatex since this tag is not related to the question. I have added symbols and math-mode instead. — leandriis, Dec 25 '19 at 14:28
Thanks for having provided a MWE. A bit more experimentation shows you can make the example even smaller. — Arnaud, Dec 25 '19 at 14:30
Actual minimal WE: \documentclass{article} \begin{document} \textbf{$H_{1,2}$:} \end{document} since the problem is not related to itemize. (As also stated by Arnaud). — leandriis, Dec 25 '19 at 14:31
@leandriis, thanks. I was thinking $H_{1,2}\ is not math symbols. I had tried \usepackage{amsbsy} and $\boldsymbol{\(H_{1,1}$}$ , not correct — aan, Dec 25 '19 at 14:33
@aan: $ starts and $ ends inline math mode See also: Are ( and ) preferable to dollar signs for math mode? — leandriis, Dec 25 '19 at 14:37
$\boldsymbol{$H_{1,1}$}$ can not work. The $ signs are not needed and \boldsymbol should be used inside of $ and $. Instead \documentclass{article} \usepackage{amsmath} \begin{document} $\boldsymbol{H_{1,2}}$\textbf{:} \end{document} would be the way to go. — leandriis, Dec 25 '19 at 14:40
@leandriis, thanks. Brillant. you can write an answer, i will need to edit my question that is not related to \itemize — aan, Dec 25 '19 at 14:42
@aan: I actually think, your question is quite similar to the one I linked in my previous comment. Would you agree closing yours as a duplicate instead? — leandriis, Dec 25 '19 at 14:44
@leandriis. Yes, you can mark as duplicated. Thanks for pointing out, i much appreciate. Even I had read the link, still hard to figure out. — aan, Dec 25 '19 at 14:45

To make the math expression bold, you need to use \mathbf{} inside the math expression (i.e. $ \mathbf{...} $ rather than \textbf{ $...$ }).

Or else, a bad way out is to use "poor man's bold" or \pmb{} in place of \textbf{} which gives you a fake bold.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath, amssymb}

\begin{document}

\renewcommand{\labelitemi}{$\blacksquare$}
\renewcommand{\labelitemii}{$\square$}
\renewcommand{\labelitemiii}{\textendash}
\begin{itemize}
   \item  \textbf{First Line}
   \begin{itemize}
     \item  \textbf{Second Line}
        \begin{itemize}
             \item \textbf{\(H_{1,1}\):} No bold starting here Third Line
             \item \( \mathbf{H_{1,1}} \): Math bold font in fourth Line
             \item \pmb{\(H_{1,1}\):} Poor man's bold in fifth Line
                %  \item {\textbf{\(H_{1,2}\):}} There 

\end{itemize}
\end{itemize}
\end{itemize}

\end{document}

to get something of this sort:

To get a bold colon (:) on the fourth line, place the colon inside\ mathbf{}, i.e. use $ \mathbf{H_{1,1}:} $.

Not related to being a third item, but to trying having math being bold with \textbf.

@Arnuad, thanks. i was thinking \(H_{1,2} is not a math symbol. – aan Dec 25 '19 at 14:34
$ ... $ is equivalent to $ ... $ (in fact there is a subtle difference, don't ask me though) – Arnaud Dec 25 '19 at 14:43
@CampanIgnis : what new question are you referring to? – Arnaud Dec 25 '19 at 14:49
@Arnoud that was an automatic comment made by the system (note the From Review link) that was generated because the reviewer (CampanIgnis) clicked the 'in my opinion this is a different question posted as an answer' option. He may have thought that you wanted to ask a new question, i.e., "how can I use \textbf to write bold math?" or something similar. That was probably a review mistake, in my opinion this is an (accurate) answer to the question, although a bit short. – Marijn Dec 25 '19 at 16:23
@Arnaud. See Marijn comment. Marion is correct. – CampanIgnis Dec 25 '19 at 21:55
