Create Form Task - Updating Textfields with values based on Dropdown Selection


I am trying to create a form where the values of the dropdown list will cause text fields to be pre-populated. For example, the dropdown list contains value1, value2, and value3. Each value has a corresponding dictionary that holds information, such as <name, Bob>. Depending on the selection made, the text fields will be updated with the necessary information. Using the key-value pair stated earlier, a text field called “name” will pre-populate with “Bob”. How can I achieve this?

I am unfamiliar with how to create Advanced Logic within the form components, so any guidance would be appreciated!

Hi @jchieng,

Please refer attached sample workflow for Action Center forms.
This contains dynamic dropdowns functionality with form task.
You can use this to customize for your requirement.

Hope this helps.


I appreciate the suggestion. I have come across this and it seems to only work for the case of conditional dropdowns where a parent dropdown will affect the child dropdown. How can I get a dropdown to affect text fields instead? The suffix “_parent” will not work on text fields from my understanding.

You could try writing JavaScript in logic of your text fields to auto populate when values in the dropdowns change.
