Anchor on bottom right, position fixed

[xumx]

Would be good to have an option to anchor on the bottom right instead of top left.

Use case: Chat window attached to bottom left of screen at the start.

position needs to be fixed.

I tried to implement something like this with different hacks, because from the box this component does not have such feature, but no luck. This problem has relation to #14 and #35 , but for now mauricius has not merged necessary PR #23 because he is developing a new version of component.
