How to "spawn" a block next to another block?

Question

JavaScript

That is, you need not just add some class to one of the many blocks (as done below), but “spawn” it next to the block in which the
PS button was pressed. only one block appears and only in the element inside which there was a click

$('.post').on('click', 
    function () {
        $('.OPa').removeClass('OPa')
        $(this).find('.post-info').toggleClass('OPa');
    }
)
