This is all done by configuring the urlId and related parameters and calling update() on the widget instances to swap them out with a different thread.

The below is an interactive example (πατήστε 'Run' πάνω αριστερά) which allows you to add and swap comment threads on demand. We could remove them as well by calling instance.destroy instead of update.

This is similar to how pagination works.

With the React and related libraries we can simply update the configuration and the library (React, Angular, Vue) will handle refreshing the widget for us. With VanillaJS we have to manage it ourselves as shown.
