      • To remove a field, click the Remove property icon.
      Tip: Any new properties that you add to the form are automatically available for all previously created treatments.

5. Add the property to the Treatment section by doing the following steps:
   1. Search for and open the CustomWebTreatmentElement extension section.
   2. Save the section into your implementation ruleset by clicking Save as.

How can I be sure that I am using effective treatments? Should I do AB testing for treatments?

The Next-Best-Action strategy uses adaptive models to determine which treatment is best and most effective. This is done by continuously testing the treatment success rate, by randomly increasing the propensity of certain treatments to allow the model to explore and learn about other situations that could yield positive results. If you use Next-Best-Action, you do not need to manually test the effectiveness of your treatments.
