Examples
Example 1
This is a simple no-frills example. You can lay the fields out in your markup however you want - but for simplicity, the rest of the examples will just put them side to side.
Country:
Region:
Example 2
Custom default option texts for both the country and region dropdowns.
Example 3
The country dropdown values are by default the same as the display values: the full country names. By adding the data-value="2-char" attribute to the country field, the values will be a 2-char character code.
Example 4
Pre-filling the fields on page load.
