Current search block: edit (-) link I'm using search api and solr, with facet api.
If I display a "current search block", if I click on a facet the system add to the block a "(-) facet name", and if I click to "(-)" it removes the facet from the search.
Is there a way to theme this behaviour? I want to display it as an image.
Look at theme_facetapi_deactivate_widget function in facetapi.theme.inc. Of course, you can override it in your theme.
