In this post, I am going to explain how to implement cascading drop-down list in the Nintex Form.
I have two SharePoint lists one with Countries and one with States
Countries:
States List : Country is a lookup column to Countries list
Demo List : have country and state lookup fields created and customize the form using Nintex Form
Nintex Form: we will be getting all the countries and all the states from the below dropdown.
To get states based on the selection of country, we need to change the settings below.
- click on the state lookup control settings. From filtering, choose “By a control’s value”, enter “Country” Manually in “Where field”, choose “CountryLookup” from “Filter by control” dropdown like below.
3. Now the state lookup will be populated based on the country lookup value selection.
