1. Is this request related to a challenge you're experiencing? Tell me about your story.

I want to create an agent application that requires users to enter multiple conditions, three of which are drop-down boxes requiring users to select their province, city, and region, and these three conditions need to have a linked effect. How can I implement this in dify? Please provide me with a reference example. Thank you very much!

Hi @jurentiancheng! I'm Dosu and I’m helping the dify team.

Dify's user input forms support dropdowns with static options, but do not natively support cascading (linked) dropdowns where the options of one depend on another. However, Dify recently introduced a dynamic-select form type, which allows dropdown options to be dynamically updated based on backend logic or workflow state. This can be used to implement cascading dropdowns, but it requires you to set up backend endpoints or workflow nodes that provide the correct options based on previous selections. The frontend will render the updated options when the backend supplies them.

To implement cascading province-city-region dropdowns, you would:

1. Use the dynamic-select type for your city and region fields.
2. When a user selects a province, your backend or workflow should update the available city options and return them to the frontend.
3. When a user selects a city, your backend or workflow should update the available region options accordingly.

Here’s a conceptual YAML snippet:

user_input_form:
  - select:
      label: 出生省份
      variable: birth_province
      options: [ ...省份列表... ]
      required: true
  - dynamic-select:
      label: 出生城市
      variable: birth_city
      options: []  # Will be filled dynamically based on province
      required: true
  - dynamic-select:
      label: 出生区县
      variable: birth_district
      options: []  # Will be filled dynamically based on city
      required: true

You must implement the backend logic (or workflow node) that listens for changes in birth_province and birth_city and returns the appropriate options for the next dropdown. This is not handled automatically by Dify’s frontend; it relies on your backend to supply the correct dynamic options at each step. There are no official documentation examples for this yet, but the feature is supported in the codebase and can be leveraged for your use case reference.

If you need a workaround and cannot use dynamic-select, some users simulate this by rendering custom HTML in the output node, but this is not a native solution.

Let me know if you need more technical details or a sample backend implementation!

To reply, just mention @dosu.
