If you want to build a team and you want only your cards to show up in the DokkanBattleBuilder, click on Search --> Saved, and the builder will immediately filter only the cards you own. The website doesn't work perfectly, when I added my cards I always had to click on "Save" twice because the first click would just deselect the blue selection from the previous card, so be sure to have actually saved your cards (you can tell from a small padlock on the bottom right corner).

But if by "User Box" you mean the user box on dbz.space, then I'm pretty sure that those are two different websites with two different accounts, and if you want your cards to show up on both websites you need to save them one by one on both. On dbz.space there's an option that allows you to upload your cards to dokkanbattlebuilder all at once (without saving them), but that's waaay to messy and time consuming, in my opinion... I can't even get the page to load, too many cards.
