When we display this to the editors in edit-mode, this is what they'll see:

The folder selection can actually be dragged directly over from the Digizuite folder structure.We also have to have a standard controller that will popular a View Model with the assets to show. We do that here:

Code Block
languagec#
protected override IViewComponentResult InvokeComponent(GalleryBlock currentContent)
{
  GalleryBlockViewModel protectedgvm override= IViewComponentResultnew InvokeComponent(GalleryBlock currentContent)GalleryBlockViewModel();
  gvm.CurrentBlock = currentContent;
  AssetQueryParameters aqm = new AssetQueryParameters();            
  aqm.Limit = currentContent.MaxNumberOfAssets;                     

  var facets = new List<FacetRequest>()
  {                   GalleryBlockViewModel
  gvm = new GalleryBlockViewModelFacetRequest();
    {
      FacetMode = gvm.CurrentBlockFacetMode.QueryOnly,
      Recursive = currentContent;false,
      SearchKey = "assetType",
     AssetQueryParameters aqmValues = new AssetQueryParametersEnums.AssetType.Image.ToString().MakeIntList();
    }
  };

  if  aqm.FoldersToSearch = (!string.IsNullOrEmpty(currentContent.Folders ?? new List<ContentReference>();))
  {
    facets.Add(new FacetRequest()
    {
      FacetMode aqm.Limit = currentContent.MaxNumberOfAssets;= FacetMode.QueryOnly,
      Recursive = false,              aqm.Page = 1;    
      SearchKey  aqm.AssetTypes= _client.Configuration.FolderMetafieldGuid.ToString(),
      Values = GlobalConstantscurrentContent.AssetTypes.Image.MakeIntList();Folders.Split(",").ToList()                   
  aqm.CropName = currentContent.CropName});             aqm.OptionalFilters = new Dictionary<string,
string>();  }
  aqm.Facets = facets;
  
  if (!string.IsNullOrEmpty(currentContent.FreeText)) aqm.FreeText = currentContent.FreeText;
     
      gvm.Images = _client.Search(aqm.CacheFor(TimeSpan.FromMinutes(1)))?.Cast<IDigizuiteImage>()?.ToList();
              return View(gvm);
        }

Notice how we also make sure to set a cache timeout of 1 minute when doing the searching? That ensures a pretty updated image list, while not cause load to the DAM server for every page view. We could probably safely increase this number a lot.
