They are separate, complementary concepts which can occur separately or jointly. The String Theory multiverse includes many different regions of space created e.g. by many pockets of cosmoc inflation, possibly with different laws of physics. Many worlds quantum mechanics posits that within universe, reality splits up whenever a "random" decision at the quantum level occurs, and there are a set of parallel realities in which all possible results of that particular process occur.
That being said, there are some smart people who claim that some inflationary multiverse scenarios can be mapped to the quantum many worlds in a kind of isomorphism between spatially parallel universes and quantum parallel universes. Kernel should like this

I'm really not convinced though that this works.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
