Vue component development: Best practices for efficient dynamic rendering of right-click menus

In Vue components, dynamic rendering of right-click menus is a common requirement. This article discusses the use of the $createElement API and a better solution - combining Teleport and floating-ui libraries to optimize the rendering and positioning of the right-click menu.

The article analyzes an implementation solution based on the $createElement API, which passes state through local components and $emit events and handles click events in the parent component. Although it is more elegant than directly operating the DOM, its parameters are fixed and difficult to deal with dynamic scenarios, such as controlling menu options based on user permissions.

The code example in the article shows the right-click menu for $createElement , but it is essentially still dynamically creating and rendering the DOM. There is no fundamental difference between pre-placing the DOM and modifying the location, but the code is organized differently.

Therefore, it is recommended to use a combination of Teleport and floating-ui . Teleport renders DOM elements to any position in body , avoiding tedious DOM operations and style conflicts. floating-ui is responsible for calculating the position of floating elements, handling various boundary situations, ensuring that the menu is displayed correctly, and there is no need to manually handle complex positioning logic. This solution more elegantly solves dynamic rendering and positioning problems, improves code maintainability and readability, and can better deal with complex scenarios such as permission control.
