Enable loading options based on neighboring values in multi-item fixed collections

The idea is:

To be able to have options loading based on a neighboring UI element inside a fixedCollection with multiple items.

The UI elements of type options can have:

typeOptions: {
	loadOptionsMethod: 'functionName',
	loadOptionsDependsOn: ['path.to.element'],
},

The loadOptionsDependsOn makes the dropdown menu reload when the value of the specified element(s) is changed. However, I didn’t find a way to have a fixedCollection UI element with multiple items which contains an options UI element depending on the value of another UI element in the same item of the fixedCollection. This is because neither of the 2 typeOptions properties have access to the fixedCollection item index. It will be useful to:

  • have access to the $index of the item in the loadOptionsDependsOn
  • have information about the parameter path of the parameter for which the loadOptions are being loaded in the in the ILoadOptionsFunctions interface

My use case:

I was able to specify a dependency between 2 options parameters in the following way:

{
  displayName: 'Field Name',
  name: 'fieldName',
  required: true,
  type: 'options',
  default: '',
  typeOptions: {
    loadOptionsDependsOn: ['additionalFields.customFields.fieldValues[0].schemaName'],
    loadOptionsMethod: 'getSchemaFields',
  },
},

where "additionalFields " is a collection and “customFields” is a fixedCollection with multiple items.

I wanted to be able to specify:

{
  displayName: 'Field Name',
  name: 'fieldName',
  required: true,
  type: 'options',
  default: '',
  typeOptions: {
    loadOptionsDependsOn: ['=additionalFields.customFields.fieldValues[{{$index}}].schemaName'],
    loadOptionsMethod: 'getSchemaFields',
  },
},

and then be able to access the path of “fieldName” (e.g. “additionalFields.customFields.fieldValues[3].fieldName”) in the getSchemaFields().

I think it would be beneficial to add this because:

This feature will allow the options UI elements to depend on neighboring UI elements when they are nested in a fixedCollection UI element with multiple items.

Any resources to support this?

I found good examples for loadOptionsDependsOn at the Teams node.

I found examples of using $index to specify the item index in the routing.send property in the WhatsApp node.
