Dynamic pages in Wix serve as templates that can be populated with data using datasets or Wix Code. These web pages are designed to display content that changes based on user interactions or database-driven information. With Wix Code, you have the ability to fetch and display data from databases, allowing you to customize the content based on user input. This functionality enables you to create interactive elements and deliver a personalized experience to your website visitors. By utilizing dynamic pages in Wix, you can easily manage and present dynamic content in a flexible and efficient manner.
