אפשר להגדיר סרגל צד מוסתר כברירת מחדל?

This is somewhat similar as the sidebar seems to be controlled by aria-expanded attribute

Way to default aria-expanded true for quoted internal links?

I’d like to show the content of a quoted post (link) by default The expand arrow is a bit too subtle. What methods do I have available to do this? Thanks [quote post]
