folding of properties/attributes #719
Description
would be great to collapse properties/attributes to remove "metadata noise".
Example from using asciidoctor reveal.js you have this block that you don't really need to see for normal editing:
[.blackback]
= Embracing a new thing :date: 2022-05-10
:revealjs_theme: white
:customcss: css/custom.css
:favicon: ./images/favicon.ico
// better
:title-slide-background-image: images/blackspace.png
:slide-background-image: images/slide2-white.png
:revealjs_fragmentInURL: true
:revealjs_hash: true
:revealjs_controls: true
:revealjs_controlsLayout: edges
:revealjs_controlsTutorial: true
:revealjs_slideNumber: c/t
:revealjs_showSlideNumber: speaker
:revealjs_autoPlayMedia: true
:revealjs_totalTime: 2700
//:revealjs_parallaxBackgroundImage: images/mntbackground.jpg
//:revealjs_parallaxBackgroundSize: 4936px 2092px
:source-highlighter: highlight.js
// leave empty or pick style from gallery at https://highlightjs.org/static/demo/ and find url at https://cdnjs.com/libraries/highlight.js
:highlightjs-theme: https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.5.1/styles/base16/solarized-dark.min.css
:revealjs_preloadIframes: true
:icons: font
Main text
would be nice to have that be:
[.blackback]
= Embracing Quarkus 3
> (attributes)
