Creating multi level lists

Hi all,

In a few WP blogs I help manage for a number of clients, I’m seeking to implement multi level lists in to text.

To be clear, this is what Word offers as its 3rd ‘bullet’ option after image bullets, and numbered bullets, and is for lists that appear like this:

1.
1.1
1.1.1
1.2
2.
2.1
3.
3.1

etc and so on, with each ‘level’ further indented.

Some of the aforementioned clients are law firms and political organisations, and want to publish regular articles with this multi level list format. Given that it’s quite a basic and common formatting style, is there a way to do this within WordPress, either via a plug-in, or code?

Thanks in advance!
