app_breadcrumbs.less
Code:
@media (max-width: @xf-responsiveNarrow)
{
.p-breadcrumbs
{
> li
{
display: none;
font-size: @xf-fontSizeSmallest;
&:last-child
{
display: block;
}
the display none hides everything, and then the last-child puts the final item back into view which is what you see.
you'll need to tweak that somehow to display what you want.
