If a list of objects exists and several independent options can be set to each object, the objects are to be listed one below the other. The options are set by the user by means of adjacent Checkboxes (Control Element). In this case, the text of the option or the checkbox appears as a column header above the checkboxes. If possible, the checkboxes appear centered below the column headers.

This guideline also applies to Radio Buttons (Control Element). The options of a line must be an affiliated group in the Screen Painter.
