In Framework7, the progress bar is used to show the loading of assets or the progress of a task to the users.
The “progressbar” class is used to specify the progress bar. “progressbar-infinite” class is used when you want to specify that user does not know how long the loading process will be there for the request.

Example
Let’s take an example to display an animated determinate and indeterminate progress bars to indicate activity in Framework7:
