Configuring forms with Smart Classifier fields
Smart classifier is a field type that allows you to build dynamic dropdowns that have a relation
Basically you will need to define a form with fields which you will use in another form through Smart Classifier field.
Let's start with a form that stores some classifier data. To make the example simple it will have only 2 fields: state and town (the number of fields Smart Classifier field supports is not limited)
Then we define another form that uses data from the one configured above
The most important is the configuration for field town in the second form.
The order of the fields specified is important, as it starts from the top to bottom. Here we configure that the state field should be the first one and it should be followed by field town
Here is how the configured "Smart Classifier" looks on a form:
