Summary:
Using Layui components and plug-ins, We can easily implement drag-and-drop search and filter functions. Through pop-up windows and form components, users can customize search criteria. Combined with the table component, we can display data and dynamically search and filter based on the user's filtering conditions. Such a function can greatly improve users' search efficiency and provide a better user experience.

The above is the detailed content of How to use Layui to implement drag-and-drop search and filtering functions. For more information, please follow other related articles on the PHP Chinese website!
