原文外掛簡介
This plugin is an addon for Contact Form 7 that lets you list Colombian departments and cities. To list departments use: [dycccf7_state department]. To list cities use: [dycccf7_city city]. The city field automatically filters its options based on the department selected in the same form.
Features
Two form-tag types: department dropdown and city dropdown.
The city list updates automatically to match the selected department.
Server-side validation confirms the submitted department and city actually belong to the official list, not just that the field isn’t empty.
Script and data are only loaded on pages where the form actually uses these fields.
Works correctly with multiple form instances on the same page.
