+        <p> 
+            By default a card restricts it's content to the card area. This means, for exmple, that if you have a select list with a lot of items, the list will be cut off at the bottom of the card.
+            You can override this behavior by setting the <code>AreaRestricted</code> property to <code>false</code>.
