You can use the **Media selection** form control to allow users to select files through page fields, when editing pages on the **Content** tab of the **Pages** application. Users can then select any file from any source – Page attachments and Media libraries.

## To insert the media selection form control

1. Open the **Page types** application.
2. **Edit** () the page type into which you want to add the media selection field.
3. Switch to the **Fields** tab.
4. Add a new field by clicking **New field**.
5. Fill in the properties of the new field as follows:
   - **Field type**: Standard field
   - **Field name**: MediaSelection
   - **Data type**: Text
   - **Size**: 300
   - **Field caption**: Media selection (for example)
   - **Field description**: any description that you want users to see when hovering over the field caption
   - **Form control**: Media selection (select via the _(more items...)_ option)
6. In **Editing control settings**, specify resizing options for images uploaded using this form control.
7. **Save** the form control.

The system creates a new column in the page type's database table. When a user inserts a link to a media using the form control, the link is stored in the column.
