Dropdown list menu

I'm developing a small web app for scanning parcels coming in to a warehouse.
I want the functionality of having a dropdownlist where I can choose shipping company to open a new site to scan parcels for this company.
I got 2 tables. Parcels and Carriers. In the Carriers table i got id, name.
1, Fedex
2, DHL
3, UPS
etc.
I want the dropdownlist to show the name. When choosing a name a new popup should open going to http://localhost:8888/Postlog/parcels/scan/<id>
How can I make a dropdown list doing this? It does'nt matter if the popup opens when choosing the name from the list or by pressing a button after.
