I've already tried adding images, but when I use Markdown headers (#, ##, etc.), they don't appear as titles but instead show the raw Markdown (## instead of an actual header).

Additionally, I’d like the structure of my post to collapse by order of importance. For example:

should be the main section (default view),

If expanded, ## should reveal its subsections, And if further expanded, ### should reveal even more detail. Currently, everything is displayed at once, and the post looks cluttered.

Also, when I use the image Markdown , I’d like it to only display the clickable text or link placeholder, not the full image inline by default. For example, this: should just show a simple clickable placeholder or text. However, what I get instead is this: I’d like it so that when I use the command , it outputs this: , instead of this: .

Improved Request: How can I ensure Markdown headers (#, ##, ###) render properly as titles in my Stack Overflow post and not as raw Markdown syntax? How can I create a collapsible structure for my post where subsections (##, ###) are hidden by default but can be expanded by the reader? How can I make images in my post appear only as clickable placeholders (e.g., ) without displaying the full image inline? Thank you for your guidance!
