how to create a item box such as in quote?

[tritian]

Hi,
how to create a item box such as in existing quote?
for example: http://demo.espocrm.de/advanced/?lan...3a4dcb0c390cb0
I thought in
/Espo/Modules/MyModule/Resources/layouts/MyModule/detail.json
or
Espo/Modules/MyModule/Resources/metadata/clientDefs/MyModule.json
but, it is not right. i find no way to create a item box in my own module.

Thank you

EDIT: now i found it in client/modules/invoice/src/views now it works... i can't delete this post...
