Showing or Hiding Tagged Values
When an element has tagged values, you can view all the respective tagged values either in a standalone box, or inline, as a compartment. You can also hide tagged values completely. To choose how tagged values should be displayed, right-click the element on the diagram, and select Tagged Values | <display option>. For example, to display all tagged values outside of the class, right-click the class on the diagram, and select Tagged Values | all. To hide all tagged values of a class, right-click the class on the diagram, and select Tagged Values | none.

When some values in a tagged values box are empty, you can hide only the empty values, as follows:
1.Select a tagged values box on the diagram (one that has both empty and non-empty values).
2.Click the Toggle compact mode 
handle in the bottom-right corner of the box.
When the handle is in expanded state , the empty values are shown as well. When the handle is in collapsed state 
, the empty values are hidden.
