</vcf-breadcrumbs>

Updates since version 2.0.0

• Lit based component with theming support.
• The first item in the breadcrumb is always shown in full.
• The items can be collapsed when space runs out. This is configurable by using the attribute collapse. When availabe space is not enough to display the full label, then the label is shown with ellipsis.
• If space is even more limited, and some breadcrumbs have the collapse attribute:
  • Consecutive collapsed items are grouped into ranges.
  • Each range is hidden when necessary and replaced with an ellipsis element.
• shift attribute from previous version was removed. Responsive behavior is now given by the collapse attribute implementation.
