A Drupal Dropdown List of Countries, States, Cities
We had a question from a member this week. He was collecting information from users and wanted to collect addresses:
“I need to have a user select a state in a list. My next requirement is to populate a new list with all the counties for the selected state.”
It’s easy to imagine many more people wanting to do something similar, so in this tutorial we’ll explain how it’s done.
This tutorial could be used to show Continents and then Countries, Countries and the States, States and then Cities or any similar combination you need. We’re going to use the Conditional Fields module.
Installation
Install the Conditional Fields module: https://drupal.org/project/conditional_fields
Yes, it is marked as a dev version for Drupal 7, but it worked for us without any problems.
Add the fields
Add your data fields as you would normally.
In this example, our first field would be a list of the US states. We’re going to add these as a List (text) field.
We enter a list of all 50 states into the field:
Now we repeat the process for the counties in each state. Start alphabetically with Alabama Counties:
And enter all a list of all the counties.
You will need to repeat this 49 more times, creating a field for each state.
Managing Dependencies
The Conditional Fields module adds a new tab called “Manage Dependencies” to the top of the fields area. Click that tab.
The Manage Dependencies tab is organized into Dependents and Dependees.
In this example, the Dependents are the counties and the Dependees are the States. Our first setup will be this:
- Dependent: Alabama Counties
- Dependees: US States
Click Add dependency.
The key setting for the field is “Insert Value from Widget”. Make sure you choose the State that will trigger the list of counties. In this example, we choose Alabama.
You will need to repeat this 49 more times, creating a dependency for each state.
Test the dependencies
Go to create a new item for your content type and see whether the dependencies are working.
In our example, only the states field will show:
However, if we select the Alabama option, then the Alabama Counties field will appear.
It would be cool to wrap it up as a feature and offer it as a download
Yes that definitely would be a neat idea for some situations:
World countries / cities
World countries / regions
US states / counties
Canadian provinces / cities etc.
I was thinking more along the lines of making a feature with the features module out of this. Conditional fields does have features integration. That way for example you could name your feature usa_field or something and have it available as a download here so people could just enable it and have that field available straight away. I’m just saying since you guys did the footwork you might as well wrap it up in a feature that way everyone can use.

Thanks Maxim
WTF??? 49 times ?!!
taxonomy + [url=https://drupal.org/project/hierarchical_select]https://drupal.org/project/…[/url]
Quite agreed. Creating 51 fields for this type of functionality is simply insane. It’d be less effort to write an entirely new field that references an API somewhere than it would be to create and populate all those fields — even if it involves learning PHP The Drupal Way from scratch along the way.
But, fortunately, the Hierarchical Select module linked to is a good deal less work than both those options. Great suggestion.
Thanks Dencho, yes doing everything through Taxonomy could be a viable alternative.
Ændrew, sadly telling people to just learn PHP is not a viable alternative.
You’re mistaking my politeness for naïveté. I’m not telling people to go learn PHP; I’m saying that a user could probably learn PHP to a serviceable level in the time it would take to simply populate all the fields this tutorial requires.
But seriously, doesn’t Location.module or something have this all pre-built already anyway?
But views integration is not available for this module.I Want Conditional exposed filters.
The [url=http://jquery.country]jquery.country[/url] plugin may helps, is a plugin for country/state/city dropdown without any use of database and server side coding. [url=http://oohm-software.github.io/jquery.country/]http://oohm-software.github…[/url]
