Freeform Text

If you ever need a feature that isn't (yet) supported, there's an easy solution: Create a freeform text element to add any text you like to your class. Text within a freeform text element does not require any specific format and does not get validated by UMLBoard, so you're free to enter whatever you need.

But please be aware that since UMLBoard does not analyze your text semantically, it does not recognize whether you reference another class within it. That means if you change the referenced class, UMLBoard cannot update your freeform text.

Use a freeform text to add an arbitrary text to your class
