Possibility to create chained select

Hi all,

child select are chained to parent select, for example you have car type on parent select which consist of “BMW, Audi, etc”. When you select BMW, then the child select will list “3 series, 5 series, 6 series, etc”. But when you select Audi, then the child select will list “A3, A4, A5, etc”.

Is it possible to create a chained select in ERPNext - Setup - Customize Form?
Please enlighten me.
Thanks in advance.

using ERPNext: v7.1.22


Perhaps you can add parents as an Item Group in your ERPNext account.

While creating transaction, if you type BMW in the Item Code field, then it will list all of it’s variants.

I don’t get it, I cannot find Item Group in the Customize Form, or in the Select type of field options.
please guide me step by step if possible.
Thanks for your time.
