Openlayers 3 map contextmenu

Question

I would like to have a right-click context menu.

those. I right-click on the map, I get a drop-down menu, here, if I chose "add marker" or something like that, I need to have a click on the position.

I think the simplest way to get the right version would be if someone could add a simple drpdown menu in rightclick to this Test Fiddle

var map = new ol.Map({
  layers: [
    new ol.layer.Tile({
      source: new ol.source.OSM()
    })
  ],
  target: 'map',
  controls: ol.control.defaults({
    attributionOptions: /** @type {olx.control.AttributionOptions} */ ({
      collapsible: false
    })
  }),
  view: new ol.View({
    center: [0, 0],
    zoom: 2
  })
});

I saw this solution, but it didn't work: https://gis.stackexchange.com/questions/148428/how-can-i-select-a-feature-in-openlayers-3-by-right-click-it

UPDATE:

(, ) . , :

contextmenu.on('open', function(evt){
  var feature = map.forEachFeatureAtPixel(evt.pixel, function(ft, l){
    return ft;
  });

  // there a feature at this pixel and I want to add
  // an option to remove this feature (marker)
  if (feature && feature.get('type') == 'removable') {

    // remove all items
    contextmenu.clear();

    // removeMarkerItem {Array}
    // propagate custom data to your callback
    removeMarkerItem.data = {
      marker: feature
    };

    contextmenu.push(removeMarkerItem);

  } else {
    contextmenu.clear();
    contextmenu.extend(contextmenu_items);
    contextmenu.extend(contextmenu.getDefaultItems());
  }
});
