Does the ContentArea have some UiDescriptor or any content type restriction?

No UIDescriptor restriction.

Used the following properties

       [CultureSpecific]
        [Display(Name = "XXXXX",
       Description = "ZZZZZZ",
       ShortName = "Content",
       GroupName = SystemTabNames.Content,
       Order = 5)]
        [AllowedTypes(typeof(YYY))]
        public virtual ContentArea ZZZ{ get; set; }

If YYY is a page type I recall the Create-option doesn't show.

Hi. I am investingating this further and I noticed behavior below.

When creating a new block from the asset pane I get the content area options viewed correctly, with both options "Drop content" and "Create new" availabe . But when I create the block from a content area  property inside a page or block, only "Drop content" is available. Notice that it is the same block type I used in both scenarios and I do not have any restrictions what so ever for required or allowed types. 

------------------ Definition of Content Area property used in both cases -----------------------------
[Display(Name = "Content Area TEST", GroupName = SystemTabNames.Content, Order = 5, Description = "this content area displays ...")]
public virtual ContentArea ContentAreaTest { get; set; }
------------------------------------------------------------------------------------------

I this behavior correct? If so, is there an option to always allow the options "Drop content" and "Create new" inside a content area property inside a block? 

Thank you

Hi Ayman, 

do you maybe remember what did you do at the end? I have the same problem. Also if you add the first block through asset pane, you can create new block directly in content area.

Hi. All being well with the configuration of your blocks then you should be able to add a child block - the 'create a new block' option will only appear when the parent has been published.

Hi. Is there a workaround to create a child block before the parent has been created/published? It's a bit cumbersome now because after creating the parent, EpiServer is navigating to the parent page of the parent block.
