TaxonomyBreadcrumb

Generates the appropriate permutation of breadcrumbs based on the specified field values, useful when needing to specify a hierarchy between those values.

This component is a result template component (see Result Templates).

This component handles both single and multi-value fields.

For example, using the following fields

• @level1 = ['a', 'b']
• @level2 = ['c', 'd']

along with the default separator will generate the following breadcrumbs based on the values of the specified fields:

• a>c
• a>d
• b>c
• b>d
