React Modal Scroll 2 Componentes superpuestos

Since the modal is absolutely positioned, it is out of the document bounds, in other words the document, does not know how big the modal is and has no idea that it is bigger than the document itself and therefore doesn't scroll.

This can be fixed by giving the modal a fixed height and setting the overflow property to scroll. Try the code below, I just tested it and it works perfectly.

    var customStyles = {
      content : {
        top: '50%',
        left: '50%',
        right: 'auto',
        bottom: 'auto',
        marginRight: '-50%',
        transform: 'translate(-50%, -50%)',
        height: '500px', // <-- This sets the height
        overlfow: 'scroll' // <-- This tells the modal to scrol
      }
    };
