If you can wrap your mind around the CAGED theory, and learn how to apply it, you will learn how basically all chords are the same, just played in different positions around the neck. Here are 6 different ways to play a B maj chord:

x24442 (A form)

x6444x (G form)

xx4477 (G form)

799877 (E form)

xx9(11)(12)(11) (D form)

x(14)(13)(11)(12)(11) (C form)

So essentially, you can move the 5 major open chord shapes all around the neck, and your index finger becomes like a capo, barring the open strings. There are many more possibilities, and it takes a little know-how to apply these shapes most effectively, but I hope this gets you starting to think about the fretboard with a new perspective.
