Hi, I'm using Block Shop by Troop Themes and want to add a 'Sort by' Filter to the top of my collection pages. Having scrolled through the community I found a github link to some HTML code. Which functions fine, but the styling is not great, the drop down box spans the entire width of the page. Does anyone have any custom css I can input to have the box smaller and placed on the right hand side?
