 * I’m currently trying the following (simplified objects):
 * I have a bunch of „objects“, which are cities. Each city has a relating country(
   even though I’m not sure how to implement this relation, yet), so for example
   I have the following cities:
 *     ```
       Stuttgart - Germany
       Berlin - Germany
       Dresden - Germany
       Paris - France
       Marseille - France
       Lyon - France
       New York - USA
       Chicago - USA
       LA - USA
       Miami - USA
       Peking - China
       Shanghai - China
       Hongkong - China
       ```
   
 * I think you get what I mean.
 * Additionally, I have some checkboxes, including the country, so in the case of
   the list provided, I would 4 checkboxes, one for Germany, one for France, one
   of USA and one for China.
 * When ticking one of this checkboxes, the relating cities should appear underneath,
   when ticking two of the checkboxes, the cities of both checked countries should
   appear, and so on.
 * Actually, I have no idea how to get this started. In a normal web application,
   I would just create a database table with 3 columns (ID, City, Country) and then
   in my frontend just react on the checkbox.change, send AJAX to a php file, which
   gets the requested objects from database (something like select * from tbl_cities
   where country=germany) and just echo them.
 * Is something similar possible in WordPress? Are there plugins for things like
   that, or how could I get this started?
 * To clarify, it’s html that should be displayed then, like a list or something,
   so if selecting germany, I would have something like a `<ul>` with `foreach($
   cities as $c){ echo "<li>".$c."</li>";}`, but I need the thing around, how do
   I get the cities and how do I react on the checkboxes and where do I store cities
   and countries
