+### Exclusive option for checkboxes
+
+Added "None of the above" exclusive behaviour to checkboxes - allowing all checkboxes in a group to be automatically unchecked when the "None of the above" option is checked.

+
+```
+<Checkboxes id="symptoms" name="symptoms" hint="Select all the symptoms you have.">
+    <Checkboxes.Box value="sore-throat">Sore throat</Checkboxes.Box>
+    <Checkboxes.Box value="runny-nose">Runny nose</Checkboxes.Box>
+    <Checkboxes.Box value="muscle-pain">Muscle or joint pain</Checkboxes.Box>
+    <Checkboxes.Divider />
+    <Checkboxes.Box value="none" exclusive>
+        None
+    </Checkboxes.Box>
