Disable headings or other specific elements of markdown syntax

[collimarco]

I have a text field in markdown, but I don't want to allow the use of headings (h1, h2, etc.).

Is it possible to disable headings recognition in redcarpet?

Is it possible to selectively enable what parts of the markdown syntax we want to allow? (e.g. allow: "bold", "italic", "list", "link" and nothing else).

there're two options:

• create your own renderer
• apply sanitize from sanitize gem with a list of desired tags
