Shopify Version Porto Theme Ver 3.6.1, Need to change Filter to be sticky and move to other place

[southminisplits]

I am trying to get the filter on the left side to look like the filter on the right side (Sister company website) I am a little newer to dev and am having a difficult time. I am using inspect element, but I am running into trouble because I am inexperienced. Anyone have any pointers? Website is southminisplits.com

Could maybe even hire someone to do it? Trying to do it but it's taking too much time.
