Hello,
The 1.17 update with region folding is out and it works. Thank you. Good day.

Thank you.
Is it possible to define multiple pairs of markers?

[pr-yemibedu]

Hello,
There are three pairs (template, style, and script) that are already defined. What else were you looking for? Thank you. Good day.

[pbaksa]

I meant multiple pairs of folding markers, like "surroundingPairs".

[pr-yemibedu]

Hello,
Are you asking about nesting the markers? It would be helpful if you gave a visual example of what you would like to see.

<template>
- upper 1
    <script>
    - inner 1
    </script>
    <script>
    - inner 2
    </script>
</template>

And if you already tried something that did not work, a screen shot would be helpful too. Thank you. Good day.

Looks like I commented in the wrong project, I assumed this is some sort of official VSCode announcement.
