创建一个不是后代或第一个节点的 Box

是否有可能创建一个与子节点或孙节点处于同一级别的框，但不是第一个节点（石油财富）的后代？想象一个名为“ABC”的孤立框，它没有从上方任何框派生的箭头。谢谢

\usetikzlibrary{arrows.meta,
                shadows}
\tikzset{arr/.style = {draw, -{Stealth[length=2mm]}},
  every edge/.style = {arr}
        }

\usepackage{lipsum}             % for dummy text filler

如果我理解正确，您可以直接使用no edge相应锚点的选项，如下面的示例代码修改所示。详细信息请参见第 44-45 页forest 包装文档。 希望这可以帮助。

\documentclass{article}

\usepackage{forest}
\usetikzlibrary{arrows.meta,
                shadows}
\tikzset{arr/.style = {draw, -{Stealth[length=2mm]}},
  every edge/.style = {arr}
        }
