Hello @MUFFANUJ ,

thank you for this feature. Looking around the preview the copy button looks good and it indeed works. However, I noticed that:

• the menu on the left side is always expanded compared to the current website
• there are some leftover code blocks which also contain output and the copy button appears. Looking it a bit closer it seems that these code blocks are not annotated as console. For exmaple, take a look at the installation guide in the block sudo ctr plugin ls | grep devmapper. Would it be possible to identify these and mark them as console?
