How do I link a dropdown in a forum to an external database?

Hi Doron,

Thank you for this, sorry I am completely new at this so need more detail if possible. The call for the service we use would be this: http://localhost:5000/service?method=xml_adoptable_animals&username=user&password=letmein

Where would I be putting this on the page so the “Animal I would like to adopt” field links to the animals from the external database? Apologies, I don’t have any experience here.

Thanks,

Anna
