Hello again,

Thank you for your reply. The code you provided DOES change the looks of the form on the desktop version alone (see image attached) – however, I would like it to look like that between 369 and 436px only. I have also tried adding your code using media queries, like:

@media only screen and (min-width: 369px) and (max-width: 436px)  {	
  body .woodmart-product-filters .woodmart-pf-checkboxes {
    flex: 1 1 100%;
    width: 0;
}
}

However, if I try it like this, nothing changes. Thank you again for your effort, I appreciate every reply.

kind Regards,
