When editing the interaction components, for example, the Popup Panel, Sliding Drawer, etc., the background will become translucent automatically. That is conducive to judging the location, placement and alignment of the components during the editing of these interaction components.

However, if you are distracted by the background, you can show/hide the background by clicking the icon at the bottom right corner. This option is available for the grouped components as well.
