  Web part title: Title of the web part displayed on the Design tab of CMS Desk and in on-site editing mode. If empty, the value of the Web part control ID property is used for this purpose.  
   

  Visibility  
  Visible: Indicates if the web part should be displayed.  
  Hide on subpages: Indicates if the web part should be hidden on sub-pages. If checked, the web part will not be displayed on documents that inherit the web part from a parent document.  
  Show for document types: Contains a list of document types on which the web part should be displayed. If the currently selected document uses the page template containing this web part, but its type is not specified by this property, the web part will be hidden. The document types in the list must be specified by their code names and separated by semicolons (;). If empty, the web part will be displayed on all document types.  
  Display to roles: Contains a list of roles to which the web part should be displayed. This may be used to implement documents with specific functionality for different types of users. The roles in the list must be specified by their code names and separated by semicolons (;). If empty, the web part will be displayed to all users.  
   

  Content  
  Path: Specifies the path of the documents that should be selected. If empty, the path will be set to all child documents under the page on which the web part is placed. Use '.' for current document selection.  
   

  Content filter  
  Document types: Determines which document types should be loaded, specified by a list of code names separated by semicolons (;). The * wildcard can be used as a substitute for a random sequence of characters. For example Product.* would include document types such as Product.Camera, Product.CellPhone, Product.Computer etc. If left empty, the web part will retrieve all document types by default. Please note that in this case (empty value), only the common data columns from View_CMS_Tree_Joined will be available. The specific fields of individual document types will not be included, so please consider this when writing transformations, WHERE conditions etc.  
  Category name: Code name of the category. Documents from this category and its subcategories will be filtered out.  
  Combine with default culture: Indicates if the default language version of a document should be used as a replacement if a given document is not translated to the currently selected language.

  Culture code: Indicates which culture version of the specified documents should be used.  
  Maximum nesting level: Specifies the maximum number of content tree sub-levels from which content should be loaded. This number is relative, i.e. counted from the start of the path specified for the content of the web part. Entering -1 causes all sub-levels to be included.  
  ORDER BY expression: Sets the value of the ORDER BY clause in the SELECT statement used to retrieve the content.  
  Select only published: Indicates if only published documents should be loaded.  
  Select top N documents: Specifies the maximum amount of documents to be loaded. If empty, all possible documents will be selected.

  WHERE condition: Sets the value of the WHERE clause in the SELECT statement used to retrieve the content.  
  Columns: Lists the database columns which should be loaded along with the given objects, separated by commas (,). If empty, all columns will be loaded. Specifying a list without unnecessary columns may significantly improve performance.

  Nested controls IDs: Must contain the IDs of any nested controls, separated by semicolons (;). For example: myRepeaterID;myDatalistID;myRepeaterID2. This property replaces the previously used NestedRepeaterID and NestedDataListID properties. If you are still using these properties, no changes to functionality will occur, but it is advisable to rewrite your code to use the new property instead. If you need to dynamically set the properties of a nested control, you have to set its DelayedLoading property to 'True'. Please note that this setting can cause problems with ViewState.
