Customer dropdown while creating new ticket

[christiaanvana]

When I create a new ticket (AgentTicketPhone) I want to have a dropdown menu with existing customers instead of typing them. How can I establish this?

typing will search in the database and fill a dropdown

This needs programming (Kernel/Output/HTML/Standard/AgentTicket(Phone|Email).dtl, Kernel/Modules/AgentTicket(Phone|Email).pm).

But what's the value of such a dropdown? If you have more than - say - 20 customers a dropdown is confusing. And imagine when you have 400 customers it's time consuming to find the correct customer and you need to know the name of the customer (or whatever information you show in the dropdown)...
