Can't make more than 2 partitions

I want to multiboot my MacBook Pro, I'm trying to make partitions but in Disk Utility I can't make my partitions, only can divide by 2? Why? It's a normal SSD not a fusion drive (SSD+HD)

Now I'm fresh installing my Mac with Internet recovery... (Second time) but this time in disk utility by internet recovery instead click on erase I clicked in partitions and make a partition named Macintosh HD

what I'm doing wrong?

Thanks in advance and sorry for my bad English because I'm Portuguese...
