Cascading Drop Downs In Nintex Forms

Topic

How do you create a series of cascading drop downs using Nintex Forms?

Instructions

Let's take a look at how to configure a three-tier cascading drop down using Nintex Forms!

 

The Setup

For this example, we are creating, in total, four lists (List A, List B, List C, and Meal Order).

 

Below is what List A -  C look like:

Notice the following:

 

  • List A contains the Single Line column 'Title' data that will feed into the 'Meal Time' List Lookup used on List B.
  • List B contains the List Lookup column, 'Meal Time' (from List A), and a Single Line column, 'Meal Type'.
  • List C contains the List Lookup column, 'Meal Type' (from List B), and a Single Line column, 'Beverage'.

 

These are the columns used when creating the list, 'Meal Order', which will be where we build our Nintex Form.

 

Below is the configuration of the 'Meal Order' list columns:

Notice the following:

 

  • The 'Meal Time' List Lookup references the 'TitleSingle Line Text column of List A.
  • The Meal Type List Lookup references the 'Meal TypeSingle Line Text column of List B.
  • The 'Beverage' List Lookup references the 'BeverageSingle Line Text column of List C.

 

Now, let's take a look at how the List Lookup Controls are configured on the Nintex Form for Filtering:

The 'Meal Time' control will not have any filtering applied, so we can move on to 'Meal Type'.

'Meal Type' is going to be filtered by the output of the control, 'MealTime' when the value of 'Meal Time' matches that of 'Meal Type'.

 

Now, let's move onto 'Beverage'.

'Beverage' will be filtered by the output of the control, 'MealType' when the value of Meal Type matches that of 'Meal Type'.

 

...the Magic.
