change reconfiguration gui content during runtime

edit

Hello,

is there a way to generate the content of the reconfiguration GUI during runtime? For instance a drop down list where it's content is decided after program start.

I know the variables are declared in the .cfg and I need to compile the package in order to get the according header files. But is it possible to assign a created parameter on the parameter server to, for instance a drop down list?

Thanks in advance, Chris
