Hello
You can follow the procedure of this link:
https://vstram.medium.com/using-hamburger-menu-in-a-mendix-native-mobile-application-5164dcf15da0
However, it seems that this sidebar menu is not officially supported in Mendix, despite the fact we have a Layout specific for that.
Hi Ivan,
you can try with https://www.npmjs.com/package/react-native-sidebar
A tutorial on how to create JavaScript for native app can be found here https://docs.mendix.com/howto/extensibility/create-native-javascript-action
Hope it helps!
Thanks & Regards,
