 You can now disable the form itself with a prop and use **isFormDisabled()** inside form elements to verify this prop.
 
+#### <a name="validate">validate</a>
+```javascript
+var MyInput = React.createClass({
+  mixins: [Formsy.Mixin],
+  changeValue: function (event) {
+    this.setValue(event.target.value);
+  },
+  validate: function () {
+    return !!this.getValue();
+  },
+  render: function () {
+    return (
+      <div>
+        <input type="text" value={this.getValue()} onChange={this.changeValue}/>
+      </div>
+    );
+  }
+});
+
+React.render(<Formy.Form disabled={true}/>);
+```
