I simply call this the Black and Grey View

How would I install this - do I download the text file and import?

Tried that - but the preview looked weird?!!!

Should have looked similar to his site.

I uploaded this style and now I'm having issues with the collapsable category buttons functionality.

Any time I select to hide or expand a category the button dissappears leaving me unable to undo my last step. Once I refresh the page the buttons reappear so I can set the category back to its original state, but once I do that the buttons dissappear again.

Is there any way to keep the buttons from dissappearing?

your link is dead

I haven't tried this one, but as long as you are running 7.0.2 you should be okay - it will not run fully on 7.1 due to additional classes being required.

I'm pretty sure it was issues with our test environment, also why the link was dead. I will update once it's been fixed.
