When I have a Box component, I want to show the width from x=0px to x=100px transparently. How can I do it?

Are you going for full transparency for the area from 0px-100px? If so, I would recommend building a custom layout modifier that clips based on a number that you pass in.

Thank you. I solved it by doing what you said.

Just saw that in a separate thread after I posted. 😅
