You can customize the form address subfields as follows:
In your Form Editor you can customize the address field anyway you like. You have the options to specify which subfields are required. The Address field consists out of six subfields. In Edit Field → Advanced you can also set which subfields will appear in the form, as well as the available countries, the instructions of the fourth subfield (region or state) and the default country.
1. To start with, simply add the Address field on your form and customize it in the Edit Field panel, on the left. If you choose to set the Address field as required, all of its subfields will also be set as required. With the option Required Subfields, however, you can set some of the subfields to be optional, by unchecking them in the dropdown list. This way, form users will no longer be restraint to fill in each subfield before submitting the form. This is very useful when you want to build a profile for each of your contacts, but do not require all of the address details.
2. If you want to change the format of the address field, go to Edit Field → Advanced and you’ll find the Country dropdown displayed on top. All means the international address format will be added on the form, while the other options will load the states, provinces or regions of the selected country in a dropdown that may be used by the form visitors. For now, we support states for the US and Australia, provinces for Canada and regions for the UK.
3. If you want to leave out some subfields from the Address field, go to Edit Field → Advanced → Visible Subfields and uncheck the subfields you don’t need, in the dropdown list. If you want to use all subfields at a later time, press Check All and all the subfields will reappear in your form.
Take note that every time you add an Address field, it will initially appear with all of its six subfields.
4. In the Country subfield you can select from 202 available countries and international entities. You can uncheck some of them in the Edit Field panel, depending on your needs. To uncheck them all, go to Advanced → Available Countries and simply press Uncheck all, on top of the dropdown list, although the United States will remain, as there has to be at least one country available. You have also the option to check all countries back.
5. You can also set the form to autodetect the country your form user comes from, based on his/her IP. Go to Advanced → Default Country and select Autodetect from the dropdown list. Now your form users will not lose their time finding their country when filling out the Address field.
6. If you want to use the Region or State option, notice that it only changes the instructions of the subfield from Region to State or vice versa. If you want to use your form on global scale, where some form users might come from region divided nations or states, such as the United States or Mexico, you could use Translations and write down your own instructions, like for example “Region/State”.
