re: enhanced categories extension and need the output to display in 2 columns. How can we accomplish this?
The list is responsive and will be up to 4 columns space permitting. Each column requires a minimum of 250px + 20px for the column gap. If you are not seeing this, then it is likely that the theme or another plugin is overriding those styles. Impossible to know for sure without being able to see the page.
re: I need to change the font for the heading and title. How can I do this?
Depends… most styles are inherited from the theme. Also, this depends on what heading and title specifically you want to change. You’ll have to provide a bit more detail and a link to the page. If yuo can share a link to the directory page, I’ll take a look.
