category filtering

const ImageGallery = () => {
  const [selectedCategory, setSelectedCategory] = useState('all');

  // Képek kategóriák szerint
  const images = [
    { src: 'image1.jpg', categories: ['nature'] },
    { src: 'image2.jpg', categories: ['food', 'nature'] },
    { src: 'image3.jpg', categories: ['animals'] },
    { src: 'image4.jpg', categories: ['food', 'animals'] },
    // ... további képek
  ];

  // Kategóriák lekérése
  const categories = ['all', 'nature', 'food', 'animals'];

  // Kategória kiválasztása
  const selectCategory = (category) => {
    setSelectedCategory(category);
  };

  // Képek szűrése a kiválasztott kategória alapján
  const filteredImages = selectedCategory === 'all'
    ? images
    : images.filter((image) => image.categories.includes(selectedCategory));

  return (
    <div>

            key={category}

            }}
          >
            {category}
