Images are not rendered and the text search field is not displayed

Hi there and, first of all, congratulations for the great job of this Wp plugin that I’m trying to use and that you can see at https://352.be7.myftpupload.com/archivio.
I’d like to submit yoy some problems I’ve found like:

– taxonomy “category” search field: in my case, this field lenght seems to be limited to 18 characters only while, on demo page screenshots(https://www.ads-software.com/plugins/wp-ultimate-search/screenshots/) it seems that a longer string like “BESCHALLUNGS-BUNDLES” (21 characters) could be used. I’d need a larger category search field so, is there a way to enlarge this field lenght?

– User text searches: even if the user textual search has been enabled and the “Check this box to enable autocomplete for user searches” has been flagged, no autocompletion is performed when I try to edit something: what is wrong?

– As you can see from my test page (https://352.be7.myftpupload.com/archivio), even if I’ve already selected the “Results with featured image tumbnails” option in the Search Results settings panel, I cannot get the tumbnails image to be rendered: how I can get the post images in the search results?

– text misalignement: as you can see from my test page, the “CATEGORY” name and the category string is misaligned while, in your screenshots it is perfectly aligned: what is the problem?

-endly, how can I change the gray colour of the drop down menu (category, Tag, Text) displayed at the click in the search area? Because I’d like to use the #f17e00 rather.

Thanks in advance for any advice and looking forward on that.

Giuseppe
