There is no possibility to display selected values of the checkbox type control in a FM template - if I have checkbox control named e.g. "mycheckbox" with some options and at least one option is checked,

${content.mycheckbox}

is not empty, but it displays "mycheckbox" string, and it is not possible to use it in #list (

[#list content.mycheckbox as mc]

throws error).

In a JSP template I can use the way described in http://wiki.magnolia-cms.com/display/WIKIARCHIVE/Displaying+values+from+checkbox+control but there is no such possibility in a FM template. Using

[#list cmsfn.nodeDataIterator(cmsfn.currentParagraph, "status") as s]

throws "freemarker.core.InvalidReferenceException: Expression cmsfn.nodeDataIterator is undefined" error.
