id=1我有一个文档模板，它使用带有/的项目列表id=0，并\begin{itemize}\onlyitems[none, include = 1]用作每个项目的显示/隐藏条件。现在我想在每个项目后添加项目符号（在列表中添加第二级）。
目标是获得相当于
text 1
\begin{itemize}\onlyitems
..
\end{itemize}
text 2
\begin{itemize}\onlyitems
...
\end{itemize}
...
无需创建新文档即可添加/删除新条目。
从列表的第一级中删除项目符号很容易，但我不确定如何更改对齐方式，以便第一级看起来像普通文本。我也不知道如何将第二级中的项目符号的样式从破折号更改为其他样式。
