Nested list in – Web application stack exchange

I am using a diagram integrated in Confluence, and it seems that I can not find a way to create a nested list. In Confluence, you can add a markup, which works, but does not seem to support that feature.

How to create a nested list of a level within a diagram?

Example (where the bullets are represented by stars):

* First
* second
* third

My desperate solution is to add blank spaces after the item in the list, until the item in the nested list goes to the next line and the level of indentation I want (horrible, does not scale, breaks easily, is inconsistent).
