Hi,

Unfortunately, the current version of Soledad doesn't support modifying the layout to match the screenshot you provided.

In case you need to hide some elements on the mobile, please go to Appearance → Customize → Custom CSS then add the following custom CSS code:

@media only screen and (max-width: 767px) {
  .single-breadcrumb,
  body.single .penci-standard-cat{
    display: none;
  }
}

Regards,
PenciDesign.
