# Linked project tasks

> [HTML Version](linked-project-tasks.html)

The widget is used to display [linked tasks](plan-items-links.md) on app forms:

- **Project Tasks**. You can open the page of a project task in the **Tasks** workspace, as well as when viewing the project plan.

- **Project Plan Element**. The user can open the page of the element when [editing the plan](create-or-change-plan.md).

The widget is placed on the sidebar of the task page. The icon to the left of the task corresponds to a certain [type of linking](plan-items-links.md#types-of-dependencies). The completed linked task will be shown crossed out in the widget. The user can also go to the page of the linked task by clicking on its name.

## Configure the widget

Let’s see how to add a widget to a project task page:

1. [Display](360009705932.md) the **Project Tasks** app in the left menu of the workspace. By default, this app is hidden.

2. Open the **Project Tasks** app view form in the [interface designer](interface_designer.md).

3. Drag the widget from the right panel of the interface designer to the sidebar of the customized form.

4. In the opened window, on the **Main** tab, the **Current Element (Project Plan Element or Project Task)\* **field is automatically filled in.

5. On the **Events** and **System** tabs, you can change the widget’s [system settings](common_widget_settings.md).

6. Save the widget settings.

7. To make the changes available to users, click **Save** and **Publish** on the top panel of the interface designer.

Similarly, you can add the **Linked project tasks **widget to the edit form of the **Project Plan Element** app.
