Joget Form Builder allows you to dynamically change the options/selections of a select box/radio button/radio based on multiple form fields value within the same form.
Tips
Dynamic Cascading Drop-Down List is also supported in List Filters too.
How it works

As shown in figure 2 in the address form, Using Form Data Options Binder, Continent field will view the values from the Continent List that contains only one column "Name", Climate field will view the values from the Climate List that contains only one column "Name", Country field will view the values from the Country List under the Name column grouped by the other 2 columns "Continent ", and "Climate".

The Field Id to Control Available Options Based on Grouping Field (figure 9) must be in the same order as the order in Grouping Column (figure 8).
Make sure to click on the Field Ids rather than type them. You should only be typing the ';' symbol.
