Custom snippets/autocomplete

Hi there,
I'm using a lot of jade with custom tags.
E.g.

<super-tag>blahblah</super-tag>

This tag has got some default attributes such as [type="furniture"] so it looks like

<super-tag type="furniture">blahblah</super-tag>

How can I add these tags to behave like an input or others that have default attributes?
(When I type input + TAB it becomes input(type="text")

I added super-tag to Jade.sublime-completions but it doesn't allow me to specify those default attributes to be shown after hitting TAB.
