Hi @everuribe,

This is a known issue of MarkdownUI. The current implementation combines multiple Text and Image views into containing layout views, which makes text selection work only at a paragraph level. I don't have a solution at the moment, but I am trying different things to make text selection work.

Thanks for the context! I guess it relies on newlines to be able to switch to a different markdown type and therefore view but maybe we can detect if it's just a continuation of the same markdown type and keep it in the same Text view? I assume this is already happening for code blocks.

It's a bit more complicated than that. It doesn't rely on newlines, as spacing is configurable per block. On top of that, styling adds yet another layer of indirection. Regarding code blocks, those are rendered in a single view, so it works as you would expect.

As a workaround, you could add a gesture to the Markdown view that displays a context menu with an item to copy the contents.

I found it's not working on Mac Catalyst
