I have to change the markup and I have to add CSS classes to themes/classy/templates/dataset/item-list.html.twig
. But only for a specific item-list.html.twig
in a specific block.
How do I create a preprocess function, which create a template suggestion for this item-list.html.twig
? So I am able to use e.g. item-list-facets.html.twig
?
