I'm using an X child theme with Icon (masonry) and would love to either display posts by category or at least add a filter by category. As I can't edit the page through the editor or cornerstone (message "managed through 3rd party plugin"), I guess the only option is html (?). I have both Essential Grid and The Grid activated before making a choice.
My global settings are full-width (no sidebar), so using the global content option is not much use and I don't really want a sidebar unless I can't filter.
Many thanks indeed!
