Use the Block Editor
You use the Block Editor to add dynamic behavior to blocks. The Block Editor provides all the tools you need to add intelligence and flexibility to your blocks.
The Block Editor has three block authoring palettes: Parameters, Actions, and Parameter Sets.
Parameters, actions, and their relationships (dependencies) are displayed in different ways in the Block Editor. You can specify settings for some of these elements.
