Vinyl Post

I started to install a vinyl fence and I have no wooden posts at the beginning, is it correct to add the wood posts after posts are vinyl set in stone??? I have another section to complete and I was wondering what is the "best" way to provide it? Put the vinyl on wood or add wood to the vinyl? Help

the idea of vinyl does not get wood. the position of vinyl can slide on the wood and must be performed only in the corners and gate posts .. hope this helps
