List

2024-04-12 07:34

Mini-program developers can use the List component and its accompanying ListItem component to create a container for list items and the individual items within a list respectively. It helps present information in a list format, providing a clean and organized interface. This topic covers the user experience, attribute details, and sample code for the List and ListItem components.
