In new version v 5.3.0 (ol map library)
Changed behavior attribution. Before I had icon "i" and under it all attribution for displayed layers.

Now I have some flattened info.

Developers gave instructions to use the previous behavior:

Attributions are not collapsible for ol/source/OSM

When a map contains a layer from a ol/source/OSM source, the
ol/control/Attribution control will be shown with the ``collapsible:
false` behavior.

To get the previous behavior, configure the ol/control/Attribution
control with collapsible: true.

But how to achieve this?

The same way as collapsible: false was specified in previous versions (note that it has always been a terms of use requirement of OSM and some other sources that attributions are always visible when their tiles are used on a public facing site)

  import Map from 'ol/Map.js';

  import View from 'ol/View.js';

  import {defaults as defaultControls} from 'ol/control.js';

  import TileLayer from 'ol/layer/Tile.js';

  import OSM from 'ol/source/OSM.js';



  var map = new Map({

    layers: [

      new TileLayer({

        source: new OSM()

      })

    ],

    controls: defaultControls({ attributionOptions: { collapsible: true } }),

    target: 'map',

    view: new View({

      center: [0, 0],

      zoom: 2

    })

  });

or if you are using the full build:

var map = new ol.Map({

  target: 'map',

  layers: [

    new ol.layer.Tile({

      source: new ol.source.OSM()

    })

  ],

  controls: ol.control.defaults({ attributionOptions: { collapsible: true } }),

  target: 'map',

  view: new ol.View({

    center: [0, 0],

    zoom: 2

  })

});

Mike I had tried

controls: ol.control.defaults({ attributionOptions: { collapsible: true }).extend([ 

new ol.control.FullScreen(), 

new ol.control.ZoomSlider(), 

new ol.control.Zoom(), ... ]),

And everything it's ok.
A huge thanks!
