I want to add an item to the ide settings, i followed this link some link and was able to add an item, but i want to add in tree structure and also import/ export functionality. Can anyone pls help.
The most simple way is to use nested elements - see e.g. how Tasks plugin settings are implemented. There are other possibilities, you may explor them starting from ConfigurableEP class.
