Need to add a column to my footer

Hello, I need to add a column to my footer - https://www.muskotech.com - I am new to Grav and have found where I control the existing columns but not how to add one. Thank you.

It depends on a theme you're using. If theme supports it, then it should be easy. If you're using some custom theme, you need to implement it via templates

In my theme there is a section that addresses the footer. But it is very rigid on options. Please the screenshots that included and can you give me your thoughts?

@tomsilver01, looks like you are using a custom theme, originally for pci-gs.com, and looking at the theme options + site footer, i guess the only built-in option left is to create nav links in the footer, so if you need anything else, you'll need theme customization

if your footer is dynamic may using blueprints as templates too, but it's static, just define in your partials templates, i.e, footer.twig
