jQuery implements the tree menu effect of custom right-click menu_jquery

The example in this article describes how jQuery implements the tree menu effect of a customized right-click menu. Share it with everyone for your reference. The details are as follows:
This is a custom right-click menu based on jQuery. When you right-click on a child node of the tree structure (no lower-level nodes), the custom menu will pop up, and the menu is automatically positioned based on the mouse position. When the mouse is clicked on any blank space outside the menu, it will automatically disappear. Here I would like to specifically explain that the so-called "outside the menu" can be dissected in two ways - 1. All positions except the mouse in the menu area; 2. The four areas A, B, C, and D as shown in the figure below. Obviously it would be simpler and more straightforward to analyze using the first method. !IsInArea in the source code represents this method.
The screenshot of the running effect is as follows:
The online demo address is as follows:
