on home I use Joomla's featured articles blog view. One of the articles contains two modules - a search form and a list. In the search form I want to place some filter drop-downs. Submitting the search should redirect to the same page (home), show the featured articles, including the filtered list.
I've tried all the submit buttons with different parameters. Also I've tried to change the search module's preferences. That's what the redirected url looks like:
For the start I would replace Joomla feature with Seblod search. You can try experimenting with hardcoding various variables in the button, but I frankly doubt this will work as it involves too many levels of nesting..
