+## Spinner
+Create a class which extends from any Android `ViewGroup` and implements [OkSpinnerAdapter.Binder](https://github.com/FuckBoilerplate/OkAdapters/blob/master/library/src/main/java/library/spinner/OkSpinnerAdapter.java). This approach allows to encapsulate the binding between the data and the `view`.
+
+ ```java
+
+public class YourModelViewGroup extends FrameLayout implements OkSpinnerAdapter.Binder<YourModel> {
+
+    public YourModelViewGroup(Context context) {
+        super(context);
+
+        View view = LayoutInflater.from(getContext()).inflate(R.layout.your_model_view_group, this, true);
+        ButterKnife.bind(this, view);
+    }
+
+    @Bind(R.id.tv_value) TextView tv_value;
+
+    @Override
+    public void bindDropDownView(YourModel model, int position) {
+        tv_value.setText(model.getValue());
+    }
+
+    @Override
+    public void bindView(YourModel model, int position) {
+        tv_value.setText(model.getValue());
+    }
+}
+
+  ```
+
+  Now instantiate [OkSpinnerAdapter](https://github.com/FuckBoilerplate/OkAdapters/blob/master/library/src/main/java/library/spinner/OkSpinnerAdapter.java) using the previous `OkSpinnerAdapter.Binder` implementation class and use it as a normal `adapter`.
+
+ ```java 
+
+    List<YourModel> items = getItems();
+
+    OkSpinnerAdapter<YourModel, YourModelViewGroup> adapter = new OkSpinnerAdapter<YourModel, YourModelViewGroup>(context, items) {
+        @Override
+        public YourModelViewGroup inflateView() {
+            return new YourModelViewGroup(context);
+        }
+    };
+
+    spinner.setAdapter(adapter);
+
+  ```
+
