How do I make the home page slider full width?

I am using the Tiffany theme and the included anywhere sliders plugin on NOpCommerce v3.6.  I would like to make the home page full width and increase the width of the homepage slider to be full width, how can I do that?

Hello,
Can you tell us which type of slider do you use? Because at Tiffany 3.6 the  
Anywhere slider has three types.

It's the Nivo slider

It should be full width. Can you please submit a ticket so we can make further investigation.

It won't let me create a ticket for the theme, there is no option in the form.

Can you check at which widget zone is attached your slider?
It should be home_page_main_slider.
