Some 1 can guide me how to change category selection screen when i create interaction.
I want that it'll be like when i creating new change - > Tree View.
I'm not sure that this makes sense as there are no Interaction "models" like you have in Change (so there could be many).
I personally don't see why would you change the single layer choice (complaint, compliment, incident, problem, request..., service catalog, service request) at the front of the OOTB interaction? All it will do is to increase the number of clicks needed to startan Interaction.
But if you have a good use-case, then I would suggest you raise an enhancement request...
