You can place a Facebook Comment widget anywhere on your page that you wish.
To add a Facebook Comment widget:
- Go to the section on your page where you want to put your Comment widget, and click the button to open the Element popup
- Scroll down and choose the Comments element from the popup
- If the Comments panel is not already open on the left, click on the Comments toolbar to open it
- In the Comments panel on the left, you'll find the Comment Widget URL, a Design tab, as well as Advanced Comment Settings, such as Visibility, which allows you to control on which devices (e.g., Desktop, Tablet, Mobile) this element should appear.
