how do I connect these 3 components with the selection key being choice?

I’m a beginner, and I’m learning to make the form. But I want to make a form based on the category selection (choice) at the top, so that the entry number and title can follow that choice.
Please explain from all of you, thank you

You can filter using screen values.

terima kasih, saya akan mencobanya dulu

thanks, I’ll try it first
