# Argument Types

Rasgo transforms use `type` within the `arguments` specification in each transform's YAML configuration file to trigger a user-friendly input in the UI.

Here's a master list of the argument types that Rasgo supports:<br>

| argument type       | description                                                                                                                                           | values                                           |
