Is dictionary type supported? Working on the realsense ROS2 wrapper, I came across an issue while trying to set "dynamic reconfigure" parameters.

For example, the parameter rgbcamera/powerline_frequency has 3 available option: Disabled - 0 50 Hz - 1 60 Hz - 2 Auto - 3

In ROS1, using ddynamicreconfigure I had a function: registerEnumVariable. Using rqtreconfigure in ROS1, it looks like that:

Is there a parallel in ROS2?

And on that note, is there an option for rqt in ROS2 to collapse parameters into groups, the way it's done in rqt_reconfigure in ROS1?
