The nuxeo-results element has a property named hideContentViewActions that is supposed to hide a certain segment of the UI (div class="resultActions"). Setting this value to true has no effect, the div is still rendered. E.g.
<nuxeo-results hide-content-view-actions="true"...
Note that, in the browser dev tools I can see that the div does have the hidden attribute, but the element is still rendered. No idea why...
