Smart list filter (customSearch filter ?) from a category page (category module link)
Hi Bernard
Yes you can 
As described here you can use defaultcat on the url to set a category filter, like:
Copy to clipboard
Search?defaultcat~5=7
where 5 is the parent category (as set in a an input in the form, e.g. {categories _parent="5" _style="select"}) and 7 is the category you want to show.
