When creating inputs in forms you can set localized labels which are translated based on the ‘Default Locale’ setting applied on the Appliance ,User or the language setting on the browser.
Setting a default locale on the appliance settings will override browser language preferences.
Menu: Administration >> Settings >> Appliance (tab)
Setting the default locale on the user settings will override appliance or browser locale settings.
To set the localized label, select the input, and on the details section, click the button next to the localized label field as shown below:
Select from the available localized labels from the list.
On the example below I’ve set the localized labels for all three inputs
When using the form on a catalog item with the default locale setting, the labels are showing in English.
Changing the default appliance locale to German will translate these labels to German.
