Implementation of Tree Menu Based on Vue3 Responsive Array and Subcomponent Recursive Application

With the continuous growth of front-end development demand, the development of front-end framework technology is also advancing rapidly. Vue. js is highly favored due to its single page component application, unique virtual DOM technology, and responsive data binding. A tree menu is a commonly used page special effect. Based on the responsive data binding and recursive application of subcomponent in the Vue3 framework, a tree menu is designed, and a complete implementation plan for the tree menu is provided using the file directory tree as an example. This solution can directly serve as a template for creating a tree menu. Any developer only needs to modify the responsive data structure on this basis to obtain a new tree menu, thereby reducing development difficulty and simplifying the development process.
