 Sometimes you may want to trigger events or modify external state when a field has been focused, so you can pass an `onFocus` handler, which will receive the id of the input that is focused and the field value.
 
+### Submit form programmatically
+You can use the reference to get your `Form` component and call the `submit` method to submit the form programmatically without a submit button.
+This method will dispatch the `submit` event of the form, and the function, that is passed to `onSubmit` props, will be called.
+
+```js
+const onSubmit = ({formData}) => console.log("Data submitted: ",  formData);
+let yourForm;
+
+render((
+  <Form schema={schema}
+        onSubmit={onSubmit} ref={(form) => {yourForm = form;}}/>
+), document.getElementById("app"));
+
+yourForm.submit();
+```
