The introduction
Sometimes the demand is so caught off guard, just the day before yesterday, the product sister proposed that the current three-level linkage between provinces and cities can no longer meet our practical application, we want to make a version to support multi-level linkage, and the interaction is like this (similar to an app) smile on the surface, the heart bitter haha.
Demand point
- Unlimited data levels
- Support multiple
- The child node has an unlimited node. If the unlimited node is selected, the parent node is selected, and the sibling node is deselected
- Parent node Displays the number of selected child nodes
Identify the requirements and move on. Move.. Dynamic… Dynamic… Dynamic… Hand! I do this by using recursive components to display columns of data according to the data hierarchy.
