### Events

| name | description |
|:-----|:------------|
| `change` | Triggered when the value of the SourceSelector changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See `.input()` for a listener that is only triggered by user input. |
| `input` | This listener is triggered when the user changes the value of the SourceSelector. |
| `select` | Event listener for when the user selects or deselects the SourceSelector. Uses event data gradio.SelectData to carry `value` referring to the label of the SourceSelector, and `selected` to refer to state of the SourceSelector. See EventData documentation on how to use this event data |
| `focus` | This listener is triggered when the SourceSelector is focused. |
| `blur` | This listener is triggered when the SourceSelector is unfocused/blurred. |
| `key_up` | This listener is triggered when the user presses a key while the SourceSelector is focused. |



### User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.

- **As output:** Is passed, passes the value of the selected dropdown choice as a `str | int | float` or its index as an `int` into the function, depending on `type`. Or, if `multiselect` is True, passes the values of the selected dropdown choices as a list of correspoding values/indices instead.
- **As input:** Should return, expects a `str | int | float` corresponding to the value of the dropdown entry to be selected. Or, if `multiselect` is True, expects a `list` of values corresponding to the selected dropdown entries.

 ```python
 def predict(
     value: str
    | int
    | float
    | list[str | int | float]
    | list[int | None]
    | None
 ) -> str | int | float | list[str | int | float] | None:
     return value
 ```
