To add a new element, click the grey (+) button which shows up as you hover next to the different items.
This opens a menu with elements for you to choose from. The selection depends on the type of item you’re adding the element to.
In general, you can add videos, images, prices, buttons, icons, maps and dividers, as well as social media buttons, text areas, titles and subtitles. Simply click on the type of element you want to add, and it’s there.
To delete an element, click on it. A mini-menu will open. Then click on the red X and your element is gone.
