Should modals be scrollable?

The goal is to keep context, therefore a modal should not take up the whole screen view. Content should fit the modal. If a scrollbar is needed, you may consider creating a new page instead.

When not to use a modal?

5. Do not use modal dialogs for nonessential information that is not related to the current user flow. As discussed above, modal dialogs have numerous disadvantages and costs to users. In order for these costs to be justified, their relevance to the task and importance should be high.

What's the difference between a modal and non-modal view presentation?

The main difference lies in the way you can interact with each screen. While a Non-Modal Screen allows users to simply go back to the parent screen, the Modal Screen requires users to complete an action before returning to the main window (“save” in our example) or cancel the current action.
