Is it possible to filter records in our view page?

e.g. I am creating a page view that shows lessons of a specific kind (e.g. reading). As all of our lessons are in the same table, how can I filter a page view so that it shows only the reading lessons, and not the writing and listening lessons, for example? I also want to see this filtered list when setting up the menu item (i.e, in the popup for selecting the specific record).

Hope that makes sense

Thanks,
Geoff

Is the lesson type a foreign key (records in another table), an enumeration field or other?
