This page demonstrates the new “Video Box” widget that ships with ClickBump 4. To add a video box to your page, just go to “Appearance > Widgets” and grab a “ClickBump: Video Box” widget. Drag it over into one of your sidebar placeholders. Header and Above Content work best, since they are usually set on the wider area of the template.
You can place a video box in a sidebar, but you probably want to hide the description to have a cleaner layout.
