Filter Layout change

Hi, I would need to change the layout of the filter component in order to make it more aesthetically beautiful by inserting comboboxes instead of listboxes … it is possible and where I have to intervene for changes …
thank you

I think there is generic code for this, and then some modules have specific overrides.

Which module do you want this for? Is it a custom module?

yes is a custom modules i need to overwrite tpl standard of filter serch
