HowTo: create custom categories in Property window ?

[Browser_ice]

Hi, I want to know how can I create custom categories in the overall ship property window ?

There are only 2 categories : stations and ships.

I which I could create sub categories inside them.

ex:
In the ship categorie, I want to create the followings:
- Trading ships
- Patroling ships
- Minting ships
- Construction ships
- ...

From there, I could collapse this sub-category to have a cleaner and easier Property window to look at.

i cannot help you with the lua stuff since i am only barely familiar with it, but as starting point this menu is created in
ui/addons/ego_detailmonitor/menu_property.lua

if you want to experiment with that file i suggest putting a copy of that file in a subst_01.cat/dat (same path and file name) and work with that - this is the same as modding in X3 with full file replacements
