Thank you for your response,
Currently dropdown section is taking too much space on the screen that is why I used this code at assets / theme.css on the bottom :-
product-grid-item-variant.product-grid-item__content {
width: 50%;
display: inline-block;
}
}
Then product images become small size kindly see the image (01), and shifted to the left align, but tittle and price text still large and in center,
Could you please help me to resolve this issue,
Thanks!
