我只想打開樹的第一個按鈕
創建級別我用這個
\pdfbookmark[0]{Start}{start}
要關閉其他級別，我使用這個
\hypersetup{
bookmarksopen=false
}
但我得到這個結果：
如何只開啟第一個按鈕？
\documentclass{book}
\usepackage[utf8]{inputenc}
\usepackage{imakeidx}
\usepackage[usenames,dvipsnames,svgnames,table]{xcolor}
\usepackage[pdftex, bookmarksnumbered, pagebackref, colorlinks=true, citecolor=Blue, linkcolor=DarkBlue!30!Black, urlcolor=Black,bookmarksopen]{hyperref}
\makeindex[columns=3, title=Alphabetical Index, intoc]
\begin{document}
\tableofcontents
\cleardoublepage
\pdfbookmark{Dedicatory}{dedic}
\chapter*{Dedicatory}
to all my family
\cleardoublepage
\pdfbookmark{Abstract}{abstr}
\chapter*{Abstract}
hello world
\chapter{chapter}
\section{Introduction}
In this example several keywords\index{keywords} will be
used which are important and deserve to appear in the
Index\index{Index}.
\subsection{subsection}
Terms like generate\index{generate} and some\index{others}
will also show up. Terms in the index can also be
nested \index{Index!nested}
\clearpage
\section{Second section}
This second section\index{section} may include some special
word, and expand the ones already used\index{keywords!used}.
\printindex
\end{document}

據我了解您的要求是只打開第一級書籤。使用 MWE，您可以將其bookmarksopenlevel=0作為選項添加到hyperref. （如果您想要開啟更深的級別，可以將 0 變更為 1 或其他值。）
透過對當前 MWE 的修改：
\usepackage[pdftex, bookmarksnumbered, pagebackref, colorlinks=true, citecolor=Blue, linkcolor=DarkBlue!30!Black, urlcolor=Black,bookmarksopen,bookmarksopenlevel=0]{hyperref}
%
我得到的顯示如下：
如果我將深度增加到 1，如下所示
\usepackage[pdftex, bookmarksnumbered, pagebackref, colorlinks=true, citecolor=Blue, linkcolor=DarkBlue!30!Black, urlcolor=Black,bookmarksopen,bookmarksopenlevel=1]{hyperref}
%
然後我得到：
