Select dropdowns are used to choose one or more options from a list.
They are commonly used for country, city, category, and preference selection.
jQuery allows reading and validating selected dropdown values easily.
This reads the selected value from the dropdown.
This validates whether an option is selected.
The change event runs when dropdown selection changes.
Dropdown Handling Notes:
- Uses val() method
- Validate default selection
