Cities dropdown widget
The plugin includes a Country dropdown widget so users can change the country with a simply click to access their content. For cities this is more complex as there are thousands of cities for each country and it's impossible to include all that data in one plugin.
But that doesn't mean your developer could custom code a solution to let your users switch between cities. We developed a demo plugin with 4 cities of Florida, USA so you can use as a boilerplate example to custom code your own solution.
You can grab the code from Github
