## Example

The following example displays a drop-down list where users may select from an account from a list of all accounts in the system. The user's selection will be confirmed via a popup.

1. In the Designer Project, [create a Flow](https://documentation.decisions.com/version-10/docs/creating-your-first-flow-2). Name it 'Get All Accounts Flow'. It will automatically open in the Flow Designer.
2. Add a **GetAll** step located via **Toolbox >** **Integrations > All Integrations > Internal Services > Account Service** to the workspace. Connect it to the Start and End steps.
3. Select the **End** step**.** In the **Properties** panel  under **Data > Pick From Current Data**, select **GetAll_Output**.
4. Save and close the Flow Designer. This Flow will gather the list of accounts to display in the dropdown list.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/image-1780425830750.png)
