Is it possible to appear in the search of all attributes regardless of category in the sidebar, since there is only one category? And how is this done?

You will have to edit plugin files. In functions.php find:
function atr_search_form($catId = '') {
  $html = '';
  $cat_id = isset($catId[0]) ? $catId[0] : '';

  if($catId <= 0) {
    return false;
  }


Replace with:
function atr_search_form($catId = '') {
  $html = '';


The issue with the appearance was resolved and thank you.

I have put two features with two subcategories. The type is Control Panels. When I search and select both categories, there are no results. If I make premium ads, then I have the results. Any idea what's wrong?

Depends how search threat multiselection.
It can be "match to all selected" or "match to any of selected".
Check attribute settings.

I have done this, with all the alternatives but to no avail. I only get results if I make premioum ads

Does not make sense.
You will have to review SQL queries on search page or reproduce issue on demo site.

It is rather a matter of operation of the add-on. When we check in the search all the features and the ad has only one of them then the ad does not appear, unless it is premium. I think this is not right because the user wants all the results of the ads even if an ad has only one feature of what he checked in the search.

Premium listings are surely not impacted by plugin, there will be no filtering at all on premiums.
I would say you have configured attribute incorrectly or you expecting something that is not provided by plugin.

Ok. Thanks for the answers. Yes, it is indeed an item I request and which can not provide this add-on. Maybe in a future version.

Describe in detail what you mean and maybe...

I mean in the future in a new version other features can be added to the add-on, including the one I wanted.
