How to split field logic in two?

[tropcicstefan]

Trying to build a theme for documentation page, specifically markdown field(Body) that represents article(DocsArticle) body, but also TOC for that article (like orchard docs right side there are links to headings). I am parsing markdown in a display driver and making a list of items in toc and passing them inside view model. Now because of html template i need to separate text of markdown field from TOC meaning I want multiple shapes to represent single field, because of structure of html in a theme

Idea was to make another display type for markdown field. Like we have Detail I wanted to make TOC display type and then in article template do something like

				{{ Model.Content.DocsArticle-Body |  shape_render }}

/* some other code */

				{% shape_clear_alternates Model.Content.DocsArticle-Body %}
				{% shape_display_type Model.Content.DocsArticle-Body "TOC" %}
				{{ Model.Content.DocsArticle-Body |  shape_render }}

That markdown field has specific 'display mode' Docs so shape type is MarkdownField_Display__Docs. So on second part when I want to render TOC one of these templates should work (MarkdownField__Docs_Display_TOC, MarkdownField_TOC__Docs_Display) or files MarkdownField-Docs.Display.TOC.cshtml, MarkdownField_Display__Docs.TOC.cshtml) but no luck I can't get them to display.

Second idea was to register another shape in driver so I had

Combine( 
Initialize... , //display shape type
Initialize("Markdowntoc", ...).Location("Detail","Content")

when i console log shape it's there meaning it should be rendered but template is always same as Detail, meaning couldn't connect different template to it. I tried Markdowntoc, Markdowntoc_Display

Any ides what I am doing wrong here?
