Smart list filter (customSearch filter ?) from a category page (category module link)
Ok for this part (having the filter set on the customSearch).
But my issue is just before that.
From the category module that generate the menu I have a link with the category name (not the id).
And so I have one for each item.
My idea is to have all link landing on the search page with the "Search?defaultcat~5=7" url parameter set accordingly.
Thanks for your time Jonny.
