# Task executor and Previous task executor

> [HTML Version](task-executors.html)

The widgets are placed by default on task pages created from the **Tasks** workspace.

The executor is always displayed on the sidebar. Information about the previous executor appears if the task is [manually reassigned](actions-with-tasks.md#reassign-task) or a [substitution is set up](substitution-add-working.md#reassign-active-tasks) for the initial executor.

You can drag and drop widgets onto the task form which is assigned in the course of a business process.



## Add a widget to a task form



You can configure both widgets in the same way. Let's see how to add a **Task executor** widget:



1. Open the required business process in the designer. Double-click the activity in which you want to create a custom form, for example, the **Task** block.

2. Open the task [form template](360029250931.md) in the interface designer and drag the widget from the sidebar onto the modeling area.

3. In the window that opens, you don't need to configure the **Main** tab. The **Context** field is intended for system processes, so leave it blank.

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

5. In the widget settings window, click **Save**. Then save and publish the business process.
