 Creating and using sub-forms in MS Access

In Microsoft Access, you can create and use sub-forms to display and manage related data in a hierarchical manner. A sub-form is a form within a form, and it allows you to display information about a related record within the context of the parent form.

To create a sub-form, you first create a main form and a separate form for the sub-form. You then add the sub-form to the main form as a control. The sub-form control displays the related data, and you can interact with the sub-form data just as you would with any other form.

You can link the main form and the sub-form using a common field, such as a unique identifier. Access will automatically display the related records in the sub-form based on the value in the common field. You can also specify the type of form view, such as single- or multiple-item view, and set the layout and appearance of the sub-form.

By using sub-forms, you can create more complex and dynamic forms that allow you to manage and display related data in a hierarchical manner. Sub-forms can improve the usability of your forms, and make it easier to work with related data, by displaying the related data within the context of the parent form.
