First, add a Section to your desired page and design it.
After designing and making the section responsive, right-click and click Save as Template.
A Library dialog box will pop up. Name the Template (Section) and click Save.
Now, Go to the page where you want to use the section and Open it with Elementor. On adding a new widget, click Add Template.
The Library dialog box will appear, and on the My Templates tab, look for the Template (Section) that you’ve saved and click Insert.
Congrats! Now you know how to use section templates everywhere on your wordpress, and it will help you develop a website much faster when you need to use the same section in other subpages.
