Final answer:
Drag and drop widgets and legacy widgets are both used to add functionality and interactivity to a website or application, but they differ in implementation and usage.
Step-by-step explanation:
Drag and drop widgets and legacy widgets are both used to add functionality and interactivity to a website or application. The main difference between them is the way they are implemented and used.
Drag and drop widgets allow users to move elements around on a webpage simply by dragging and dropping them. This can be useful for creating interactive user interfaces and organizing content in a flexible way.
Legacy widgets, on the other hand, are typically pre-built components that perform specific functions or display specific information. They are often added to a webpage through the use of code or a pre-defined template.
