# Sources

The sources section helps you prepare an option list for an input. There are 2 types of sources,

| Type    | Description                                   |
| ------- | --------------------------------------------- |
| static  | pre-defined and fixed option list             |
| dynamic | request a dynamic option list via an API call |

### Create Source <a href="#create-source" id="create-source"></a>

Follow steps 1 to 7 in the above screenshot to create a source and start editing. Once a source type is selected, you are unable to change it.

### Static Source <a href="#static-source" id="static-source"></a>

Click on **Add Item** to add as many options as needed. The label is what to display to users and the value is what will be actually stored in the app field.

### Dynamic Source <a href="#dynamic-source" id="dynamic-source"></a>

Configure the [external request](/help-center/flow-builder/advanced-actions/external-request.md) to get the option list.

Specify the path for the whole list first, and the **relative** paths for getting the value and label in each item of the list.

### Use Source <a href="#use-source" id="use-source"></a>

Sources can be used wherever you edit an input item:

Choose **Select** in the input type and pick a source in the drop-down list.

This is the user interface for a static source and dynamic source in a web form:
