To create a component template, simply highlight the component group you'd like to create into a template. You can also select the parent component (either a card or an image) containing different components.
After selection, click on 'Create template' on the lower right-hand side of the screen. Alternatively, you can also right-click while on your canvas and choose 'Create template.'
You will be asked to give your component template a name. After typing out the name, click 'Create template' to confirm component template creation.
