Hello,

It is not possible to show breadcrumbs having hidden the page heading. You can hide the page title with custom CSS and leave the breadcrumbs.

If you want to hide page title on once certain page add the custom CSS to page settings field http://prntscr.com/k7kztf :

.page-title.color-scheme-light .entry-title {
   display:none;
}

In order to hide page title globally, add this code to Theme Settings > Custom CSS

Best Regards
