+## FAQ
+### Can I get context in the component tree in a modal?
+Yes. To get the data from context in the component tree you need to use the declarative way. For example:
+```jsx
+export default function AntdSample() {
+  return (
+    <>
+      <Button type="primary" onClick={() => NiceModal.show('my-antd-modal', { name: 'Nate' })}>
+        Show Modal
+      </Button>
+      <MyAntdModal id="my-antd-modal" {...otherProps} />
+    </>
+  );
+}
+```
