Improve structure selection when creating relay account

B2B online shop now allows you to easily link your Structure when creating a new relay contact:

• Link a Structure with typing Structure full name (or Structure number as before)
• Immediately know whether your Structure exists or not in the on-going contact creation

Notes:

• For security reason, the search result (list of Structure) while typing Structure name is not applied, you have to enter your Structure full official name.
• If the full name is shared by more than 1 Structures, you are required to input the Structure number instead.
