Hello together,

i´m new to Odoo and i want to develop a own modul in Odoo Version 12.

The main functioniality should be to select a number of contacts, which have been created in the Contact sub menu of Odoo(so technically it sould be res.partner in the Database). The selection shall be performed in a dropdownlist or a field where contacts can be added (like the purchase setup in invoice).

After the selection i want to perform an action with the data of the selected contacts on the button click, how can i transfer the data from the view to buttonfunction.

Some Examples or maybe a implemented Version would be much appreciated. So i can rebuilt this to match my expectations or needs for the

Any help would be much apprecticated I´m struggling on this for serveral days.
