Answer 1

That is implemented by using modal, you can use custom html in your admin form. here is normal example for basic html implementation:
.modal.left .modal-dialog,
.modal.right .modal-dialog {
position: fixed;
margin: auto;
width: 320px;
height: 100%;
-webkit-transform: translate3d(0%, 0, 0);
-ms-transform: translate3d(0%, 0, 0);
-o-transform: translate3d(0%, 0, 0);
transform: translate3d(0%, 0, 0);
}
.modal.left .modal-content,
.modal.right .modal-content {
height: 100%;
overflow-y: auto;
}
.modal.left .modal-body,
.modal.right .modal-body {
padding: 15px 15px 80px;
}
/*Left*/
.modal.left.fade .modal-dialog{
left: -320px;
-webkit-transition: opacity 0.3s linear, left 0.3s ease-out;
-moz-transition: opacity 0.3s linear, left 0.3s ease-out;
-o-transition: opacity 0.3s linear, left 0.3s ease-out;
transition: opacity 0.3s linear, left 0.3s ease-out;
}
.modal.left.fade.in .modal-dialog{
left: 0;
}
/*Right*/
.modal.right.fade .modal-dialog {
right: -320px;
-webkit-transition: opacity 0.3s linear, right 0.3s ease-out;
-moz-transition: opacity 0.3s linear, right 0.3s ease-out;
-o-transition: opacity 0.3s linear, right 0.3s ease-out;
transition: opacity 0.3s linear, right 0.3s ease-out;
}
.modal.right.fade.in .modal-dialog {
right: 0;
}
