Typed markdown properties

[gitFoxCode]

Is it possible to typecast property data so that available options appear while typing, similar to an Typescript Enum? For example, layout: "default" | "page" | "blog"? without using an additional application like Nuxt Studio, I would prefer to have everything in Visual Studio Code. Is there any extension for this?

This would be helpful for non-technical people, or even for technical people in a large project.
(until the wysiwyg editor like Notion, which is expected to be developed in the future)
