            Three common ways for a prospective owner to acquire a dog is from pet shops, private
            owners, or shelters.

            A pet shop may be the most convenient way to buy a dog. Buying a dog from a private
            owner allows you to assess the pedigree and upbringing of your dog before choosing to
            take it home. Lastly, finding your dog from a shelter, helps give a good home to a dog
            who may not find one so readily.

      </Accordion>

Or you can add icon to the title field

const panel1Panels = [
            { key: 'panel-1a', title: (<div><Icon name='edit' />'Panel 1A'</div>), content: 'Panel 1A Contents' },
            { key: 'panel-1b', title: (<div><Icon name='add' />'Panel 1B'</div>), content: 'Panel 1B Contents' },
        ];
