How to add dynamic fields based on dynamic dropdown selection?

Here’s an example that demonstrates what you’re trying to do: 

Have a look at that and let us know if that doesn’t get you up and running.

Thanks for your comment. How can I pass “Vehicle Type” field say “type” from Vehicle Type API so then your “Marker Dropdown get the value as you have mentioned in code.

```

url: 'https://example.com/vehiclemaker',
  method: 'GET',
  headers: {
    'Accept': 'application/json',
    'x-api-key': bundle.authData['api_key']
  },
  params: {
    'type': bundle.inputData.type
  }

It’s helps a lot.

How can I pass “Vehicle Type” field say “type” from Vehicle Type API so then your “Marker Dropdown get the value as you have mentioned in code.

The code snippet you posted shows this - you can reference the user’s selection in bundle.inputData.type.

Note this specific example might actually be better served by using dynamic dropdowns instead: 

But you mentioned you wanted to create entirely different sets of fields based on the user’s selection, so this dynamic fields example shows how to do that - just build a set of fields rather than a single dropdown.

I already have two triggers say “Provider” and “Voice” from where I have collected the detail of two Dropdown by Webhooks.

Now I have set up an action ABC with input Designer “Provider” as Alter Dropdown field and “Voice” as dynamic Dropdown. So my concern, how can I make a relation between these two Dropdown so depending on the selection in Provider, Voice will have different options within it?

OR how can I call an API  of Provider downdown list (like javascript onChange Event) to get detail of “Voice” field and populate in Voice Dropdown?

I have create a trigger Get Voice list with key “provider” and API polling configuration

```
const options = {
  url: 'www.example.com/VoiceAllLists',
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'X-API-KEY': bundle.authData.api_key
  },
  body: {
    'api_key': bundle.authData.api_key,
    'provider': bundle.inputData.provider
  }
}
```
 

Then In ABC action I have same Input Field with key “provider” and  once I choose a value from  Provider downdown list (like javascript onChange Event) , Voice dropdown field comes with no “No option available”

Now dynamic dropdown works but auto refresh Voice dropdown list based on onChange event of provider field.
