How do I create a custom menu?

[Muttley Creations]

Hello dear friends, I would like to understand the system for creating menu options and submenus through sprites.

Example:

;---ARCADIAN
menu.bg.menuarcade.spr = 25.0
menu.bg.menuarcade.offset =-80,-15
menu.bg.active.menuarcade.spr = 25.1
menu.bg.active.menuarcade.offset =-80,-15

menu.bg.menuarcade.arcade.spr = 25.0
menu.bg.menuarcade.arcade.offset =-80,-15
menu.bg.active.menuarcade.arcade.spr = 25.1
menu.bg.active.menuarcade.arcade.offset =-80,-15

menu.bg.menuarcade.teamarcade.spr = 25.0
menu.bg.menuarcade.teamarcade.offset =-80.15
menu.bg.active.menuarcade.teamarcade.spr = 25.1
menu.bg.active.menuarcade.teamarcade.offset =-80.15

menu.bg.menuarcade.teamcoop.spr = 25.0
menu.bg.menuarcade.teamcoop.offset =-80.45
menu.bg.active.menuarcade.teamcoop.spr = 25.1
menu.bg.active.menuarcade.teamcoop.offset =-80.45

menu.bg.menuarcade.back.spr = 25.2
menu.bg.menuarcade.back.offset =-80.75
menu.bg.active.menuarcade.back.spr = 25.3
menu.bg.active.menuarcade.back.offset =-80.75

How can I activate this functionality in Ikemen?
