The FlexibleForm class represents a set of fields that you can move as a group or independently of each other. Unlike the SubForm class, the bounding box for a flexible form conforms to the locations of the fields rather than constraining them.

Typically, a flexible form is a convenience for editing only. You do not need to name it because OpenROAD considers all named fields within the flexible form as part of the form (or the composite that contains the flexible form).

If you do name the FlexibleForm, you must use dot notation to see its components (for example, flexform.entryfield).
