want to find an example of a list
click on a list of Tibetan dishes that can click on the right button to appear to the left
and then go back to the right when you take it back
I don"t know what keywords to use to check
what is the name of this technique?

$(".closeRightLayout,.add_layout_after").click(function(e) {

  $( ".rightLayout" ).animate({
    opacity: 0.5,
    right: "-300px",
    height: "toggle"
  }, 300, function() {
    // Animation complete.
  });

  $(".rightLayout,.add_layout_after").fadeOut();
});
$("-sharpadd_tab").click(function(e) {

  $( ".rightLayout" ).animate({
    opacity: 1,
    right: "0",
    height: "toggle"
  }, 300, function() {
    // Animation complete.
  });

  $(".rightLayout,.add_layout_after").fadeIn();
});

I wrote a code like this
when he came out, he was very busy
, but when he went back, he would soon
. It was all 300ms.
