将鼠标悬停在按钮上时如何在按钮上显示列表

Question

我有一个按钮，当您将鼠标悬停在按钮上时，我想为其命名。同时，我希望更改背景并在按钮上显示一个列表。

    .buttons{
            width: auto;
            position:horizontal;
            font-size: 0;
            background-color: darkslategrey;
            border-radius: 10px;
            }

        .buttons .btn-1{
            display:inline-block ;
            border-radius: 8px;
            background-image: url("/img/teatritood.JPG");
            cursor: pointer;
            background-size: 100%;
            border: none;
            padding:none;
            height: 30rem;
            width: 33.3%;
            font-family: 'Courier New', Courier, monospace;
            color: whitesmoke;
            font-display: bold;
            font-size: 30px;
            box-shadow: inset 80px 80px 80px darkslategrey, inset -80px -80px 80px darkslategrey;
        }

        .btn-1:hover{

            background-image: url("/img/teatritood.JPG");
            cursor: pointer;
            transition-duration: 0s;
            background-size: 100%;
            border: none;
            padding:none;
            width: 30.33%;
            height: 30rem;
            font-size: 0px;
            box-shadow: none;
            box-shadow: inset 10px 10px 10px darkslategrey, inset -10px -10px 10px darkslategrey; 
            }

        .btn-1:hover::after{

            display: block;
            content: attr(data-hover);
            font-family: 'Courier New', Courier, monospace;
            color: whitesmoke;
            font-display: bold;
            font-size: 38px;
            transform: rotateY(180deg);
        }
