This commit changes the way the identification questions (name, email, phone) are asked when registering to an event. They aren't hardcoded anymore and can be created per event the same way other questions can be. They can be set as mandatory or not and the order can be changed. One can now also ask for the attendee company name. Task-3056380 closes odoo/odoo#112164 Related: odoo/upgrade#4313 Signed-off-by: Warnon Aurélien (awa) <awa@odoo.com>
