重新格式化目录树样式

我有一个目录树，几乎看起来像这样：

样本目录树

上面的图片是我想要实现的。这是我在帮助下稍作修改后得到的制作（简单）目录树

我的目录树

我知道我应该再努力一点，但在制作图表方面，尤其是与复杂树相关的图表方面，我并不是专业人士。在这里，我正在寻找一种方法来使除主节点（或根节点）之外的每个节点的背景颜色变为灰色。主节点应该如图所示具有框。另外，我在寻找一种方法来任意修改节点，使其具有像主节点一样的框，如图中间和底部所示。另外，左边的小框应该有一个减号（展开形式）。顶部的标题是可选的，图像末尾的行将被忽略。只要方便，使用哪些包并不重要。

更新

fill我设法通过使用、inner sep和s sep以及编辑节点来模拟扩展形式来稍微改进我的图片edge path。现在我需要一点帮助来使边缘路径类似于第一幅图像。

这是我的代码：

\documentclass[border=5pt]{standalone}
\usepackage{forest}
\usepackage{xcolor}

\definecolor{mygray}{RGB}{224,224,224}
\begin{document}

\begin{forest}
  for tree={
    font=\sffamily,
     if level=0
      {fill=white,draw=black}
      {fill=mygray,draw=black},
    grow'=0,
    child anchor=west,
    parent anchor=south,
    anchor=west,
    calign=first,
    inner xsep= 15pt,
    s sep=15pt,
    edge path={

答案1

如果我理解正确的话，这里有两个问题。首先，-只有当子文件夹有子项时，节点才应出现。其次，其他子项的边不应绘制在节点上-。

对于第一个问题，我们可以使用if n children条件。如果没有子节点，我们就设置一条简单的边路径，不带节点；否则，设置一个带边框的边路径-。

第二个问题可以通过改变绘制边缘的顺序来解决；必须从最后一个子节点开始绘制子节点的边缘。这可以通过设置draw tree edges processing ordernodewalk 样式（参见手册第 3.4.3 节）到tree reversed（第 3.8.3 节）来解决。

以下是完整的更新代码：

  for tree={
    font=\sffamily,
     if level=0

      {fill=mygray,draw=black},
    grow'=0,
    child anchor=west,
    parent anchor=south,
    anchor=west,
    calign=first,
    inner xsep= 15pt,
    s sep=15pt,
    if n children=0{

在此处输入图片描述

-更新：在根的左边也画出来

我认为，最好手动执行此操作：将根稍微向右移动一点，然后将放在-它的左边。问题在于根的子节点连接到根节点；解决方案：概括边缘路径分配以支持任意移位，并将其分别应用于根的子节点。
