I notice that in the wordpress description of the theme at https://wordpress.com/theme/moka, it shows a large search widget, and a large “filter by category” widget. I’m having trouble finding these to add them to my site. Am I just overlooking something?
I think you found the search option already, or? The filter by tags option can be added to the Moka widget area, just add the “Tagcloud” widget here. Is this helpful or did you mean another area of the Moka live demo?
