+        <label for="checkbox1">Checkbox</label>
+    </div>
+
+The `data-checked` attribute may have one of three values: 0 (off), 1 (indeterminate) or 2 (on).

+            <li data-value="2">Two</li>
+            <li data-value="3">Three</li>
+        </ul>
+
+        <input type="hidden" name="balloonValue" value="1" />
+    </div>
+
+If you don't define `data-control="balloon-selector"` then the control will act as a static list of labels.
+
+    <div class="control-balloon-selector">
+        <ul>
+            <li>Monday</li>
+            <li>Tuesday</li>
+            <li>Happy days!</li>
+        </ul>
+    </div>
