Filtering a table on the front end

Hallo

I'm trying to get familiar with chronoform 7.
Implementing the basic instructions I've found somewhere in this site, I've been able to display the content of a table contained in my Joomla db, creating a connectivity form.
What I want to do is to add a section at the top of this table with a number of boxes (Dropdown and text fields) in order to allow the user to filter the content of the table.



by clicking on the button "Applica filtri".

Thanks for any indication or suggestion
