function facetapi_item_list_build in Facet API 6

Recursive function that converts the render array into an array that can be passed to theme_item_list().

NOTE: In Drupal 6 theme_item_list() does not accept an array, so the wrapper function theme_facetapi_item_list() must be used.

Parameters

$build: The render array for the facet's items.

Return value

An array that can be passed the theme_item_list().
