Apache Solr for TYPO3 CMS

A Conditional Facet is a facet, that is shown only if a certain condition is fulfilled. As a starter lets say we show a facet only if a defined option of another facet is selected.

configuration example:

plugin.tx_solr.search.faceting.facets {
  facetA {
    field = a
    label = A
  }

  facetB {
    field = b
    label = B

    condition.facetOptionIsSelected = facetA[optionX]
  }
}

When implementing this, a tx_solr_facet_Facet class should be created, too to avoid duplicate code like the isActive() method in tx_solr_facet_AbstractFacetRenderer which would be useful for this purpose.
