How does the mini-routine subcomponent button call from submission?

as shown in the picture, yellow is a large page, and red is a component that introduces (components), and wraps the red component with from tags. Now I want to use the button of the red component to trigger a yellow from submission event. Is that okay? How should it be realized?
