You can use our [Ops Explorer dev tool](https://tray.ai/documentation/developer/developer-tools/operations-explorer) to get a very quick view of these.

Please also see our [Building a UI form tutorial](https://tray.ai/documentation/developer/getting-started/tutorials/building-a-ui-form/) for guidance on rendering these.

For example the Salesforce 'Find records' operation has enum list for the filter conditions:
