By default, contents are displayed in Boomla vertically, one after the other. This app displays all contents horizontally next to each other.
Note: the red images are for demonstration purposes only, they each stand for a content. They are not part of the horizontal container app.
Normal content flow
Note: stretch affects the space available for the content. It doesn't mean the content will be automatically stretched, it is up to the application to support this functionality when it makes sense.
When the contents do not fit in a row, they are wrapped into multiple rows
