Creating a Menu - ellis-matthew4/XDL GitHub Wiki
Menus in XDL are different from RenPy. The main difference is the use of the "option" keyword. This is what a menu declaration looks like:
menu:
option "Option 1" <call||jump> labelName1
option "Option 2" <call||jump> labelName2
Where it says <call||jump>, simply write either call or jump, depending on which protocol you want to use.
