I repost some of my blog posts made @ liip. Please see here for the original post and comments: https://blog.liip.ch/hackday-for-symfony2-cmf.html

Last week we had a hackday on the Symfony2 CMF. We played with the first CMF sandbox and made it do some basic things. You can see the result with some simplistic cms at our sandbox clone. It just shows a node (at route /cms/<path>), assuming you first created some nodes (at /admin). Along with the node itself, we show the breadcrumb and child nodes, to demonstrate how the hierarchy can be used.

The next step is to provide a tree walker service in the CMF sandbox, that can one day become a core component of the CMF, allowing some basic tree walking operations that make sense with a CMS (parents, children, parents-and-siblings for a menu open at the current node).

If you are interested in contributing, clone our liip sandbox and play around with it (note that - Symfony2 being currently a moving target - the repo is currently broken because of upstream changes, i hope to fix this tomorrow) . Or clone the main sandbox and try stuff on your own.
