Course Introduction：How to use Element-UI in Vue to implement multi-stage linkage drop-down boxes? Use multiple El-Select components to bind data through v-model and use logic to control dynamic changes in options. Use a recursive function to efficiently generate and update the option list, dynamically update the options for subsequent drop-down boxes based on the selection results. Pay attention to the design of the data structure. A clear data structure can simplify the code logic. Considering performance issues when the data volume is large, use tree structure or virtual scrolling technology to optimize rendering. Handle errors to avoid program crashes.

Course Introduction：The main problems with the Vue and Element-UI cascaded drop-down boxes are caused by data structure errors, improper asynchronous loading and value update issues. First, the cascading selector requires a tree-like data structure, the data contains label and children attributes. Secondly, when loading data asynchronously, you must use Promise and use functions on the options attribute. Finally, double check the correctness of v-model binding and @change event handling.
