The wiki has an ugly trick. If the box is inside a < pre > text < / pre >, it shows up in a grey box and is preformatted. If the pre tags are taken off AND the first character of a line is a space, you keep the grey box, but can use bold, urls, strikeout, etc markup tags or wiki tags with a preformatted spacing. If the first character of the line is not a space, then you are outside the grey boxes and get a slightly different markup style with a flowing spacing.
Edit: I removed the pre tags and it showed up just like you wanted.
You can add a new section by going in to the source mode, then adding three equal signs, title three equal signs, like
===New Block===
