A dictionary is a list of values for a given type of field, e.g., localizations, that can be used in selected forms in Traffit, e.g., in candidate profile.
There are two types of dictionaries: one is defined by us with no option to edit, but with the option to add your own values, and the other is dictionaries created by users from scratch.
You can create as many dictionaries as you need and tie them to single and multiple-choice fields.
