Wrong indentation when editing Yaml in Vim

Question

Vim does not seem to correctly react at a dash symbol in YAML files therefore breaking the format.

For example I have a block which should look like this:

Answer 1

In order to get the nice 2-space YAML as the default when I hit carriage return after the colon, I added this to my .vimrc:

autocmd FileType yaml setlocal ts=2 sts=2 sw=2 expandtab

This also plays nice with the dash for the OP's expected result.
