Hi @Suraj_Kamdi ,
When you create SPA react component, you have to wrap the component B in render() of component A in the react code itself. You can refer react articles for component embedding and wrapping.
The only concept while embedding would be passing the required props to component B(fixed component) from component A(to be configured component).
One of the tutorials you can refer : https://www.pluralsight.com/guides/how-to-wrap-one-react-component-into-another
You need to import the componentB in componentA.
pseudo render():
//ComponentA render()
<div class="this-is-componentA-parent">
//some html for component A here...
<ComponentB expectedProp={props.propertyConfiguredInComponentA} />
</div>
Let me know if you still have any further concerns.
Thanks.
