Comment thread (full page)
Consider using a full-page UI for discussion threads to maximize usability. This design makes it easy to read longer posts and to skim long threads by scrolling.
You may also use this pattern at the bottom of a page, below other content.

Comment thread (widget)
Use this pattern to display a comment thread alongside other related content.
Display comments in their own column or at the bottom of the page so that users can skim long threads by scrolling. While you may add paging controls for traversing long threads, aim to minimize the need to paginate.

Dual picklist (simple)
Use this pattern on a form to allow users to select one or more items from a moderately long list of available choices.
Use standard checkboxes instead for short lists of available choices.
Use pickers instead for very long lists of available choices that cannot easily be browsed by scrolling.
