Can I access component/placeholder hierarchy from a `getPlaceholderRenderings` processor?

Question

Our solution is using dynamic placeholders. We have a requirement to restrict what renderings can be inserted in the page content (under the content placeholder) and in the sidebar (placeholder right-sidebar). The restriction should be applied on all nesting levels.

What I'd like to do is make a custom getPlaceholderRenderings processor which would return allowed renderings of the content placeholder for every placeholder rendered inside content. The challenge is in finding out the part of the page the placeholder is being rendered in.

Answer 1

GetPlaceholderRenderings pipeline will be executed for each placeholder on the page so you will be able to process each nested placeholder and a make decision about available renderings.

Your Process method accepts GetPlaceholderRenderingsArgs type as an argument.

GetPlaceholderRenderingsArgs type contains:

• PlaceholderRenderings - list of Rendering items.
• PlaceholderKey - current placeholder path

PlaceholderKey returns a placeholder path (not single placeholder key), so you can check whether your currently processed placeholder is nested under content/right-sidebar.
