This group allows to set how to work with containers and their nested elements. There are three possible ways how to add elements to a container:
- Partially overlapped elements (11) - an element will be added to a container when they are intersected at the end of moving.
- Fully overlapped elements (12) - an element will be added to a container when its bounds are fully contained by container at the end of moving.
- When cursor over container (13) - an element will be added to a container when the cursor is over the container at the end of moving.
Ask for container inflation (14) - if checked, dialog will show which allows to choose whether to inflate the container with overflown elements or not.
Auto inflate (15) - if checked, the bounds of container will be automatically enlarged to include a newly added nested element.
