Hi jeremypthompson,
This is somewhat involved but not too bad. I would suggest first setting the Events Template in Events > Settings > Template to one of your theme’s templates with a sidebar. Then you just need to add some CSS to hide the sidebar on the calendar page and make everything full width. To help with this, you can specifically target the gridview page with the .events-gridview body class. So in your CSS you would use something like this to hide your sidebar:
.events-gridview #sidebar {
display: none;
}
Then, you just need to modify the container widths on the page in a similar way. I would need to look at your code with the chosen template in place to tell you for sure what to do. If you want to apply the template you’re going to use I can take a look and give you a better idea of the CSS to apply to get the page full width.
Let me know if that helps.
