# Adding Conditions to HHD Implementations

> How to add custom conditions to Handheld Device implementations to control user access to specific screens and enforce custom rules.

## Customising HHD flows with conditions

You can add conditions to your Handheld Device (HHD) implementation to control which screens users see or to enforce custom rules based on defined parameters -- for example, restricting a specific account from accessing a particular screen.

<Steps>
  <Step title="Navigate to the implementation">
    From the **Handheld Devices** tab, go to **Implementations**. Select the implementation you want to modify.
  </Step>

  <Step title="Preview the flow">
    Scroll down to the **Preview** section. This shows a simulated view of the scanner screen. Click any option in Preview mode to simulate its functionality.
  </Step>

  <Step title="Edit a screen to add conditions">
    On the desired screen, click the **Edit** button. New icons appear next to each option:

    * **Plus sign (+)**: Add new conditions or components
    * **Pencil icon**: Edit existing components
    * **Trash bin**: Delete existing components
    * **Arrow icon**: Navigate into the selected option
  </Step>

  <Step title="Add a condition">
    Select an existing component. A panel appears on the right-hand side -- navigate to the **Conditions** tab. Click the **Plus (+) sign** next to **Component Conditions** to add a new condition.

    Define the condition parameters. For example, set `task_account_code` **is equal to** `JOSEPH`. This means only users on that account code will see the relevant screen content.
  </Step>
</Steps>

<Accordion title="FAQ">
  **Why would I need to add a condition?**

  To restrict a specific account from accessing a particular screen, or to introduce custom rules that control the HHD flow.

  **What do the different icons mean when editing a screen?**

  Plus (+) adds new conditions or components. Pencil edits existing ones. Trash bin deletes them. Arrow navigates into the selected option.
