Toggle Class Only in One Parent

Question

I have the code below that changes the class of a selection so that the user can only select one out of all the options. When there's one set of products per page, it's easily done but when I introduce two sets or more, the users can only select one between multiple groups.

I need a way to ensure that the toggling of the class only applies within the parent div of each button.

I.e. a user can select button 1 and button 3 but not button 1 and 2 or button 3 and 4

Updated

Only the product sets can have IDs

Products themselves as well as buttons can't have individual IDs

var box = $(".Button");
box.click(function() {
  $(this).toggleClass("Green");
  box.not(this).removeClass("Green");
});

.Label {
  font-weight: 600;
  padding: 5%;
  font-size: 16px;
  float: center;
  position: relative;
}

.Button {
  font-weight: bold;
  font-size: 13px;
  background: #0096db;
  text-align: center;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
  padding: 15px;
  color: #fff;
  position: static;
  float: left;
  min-width: 25%;
  max-width: 40%;
}

.Button.Green {
  background: #64B448;
  font-weight: bold;
  font-size: 13px;
  text-align: center;
  border-bottom-left-radius: 5px;

  color: #fff;
  position: static;
  float: left;
  min-width: 25%;
  max-width: 40%;
}

.productset1 {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 2fr));
  grid-template-rows: repeat(auto-fit, minmax(10px, 1fr));

Only look for other buttons within the parent:

var box = $(".Button");
box.click(function() {
  var $this = $(this);
  $this.toggleClass("Green");
  $this.parent().find(".Button").not(this).removeClass("Green");
});

Example:

var box = $(".Button");
box.click(function() {
  var $this = $(this);
  $this.toggleClass("Green");
  $this.parent().find(".Button").not(this).removeClass("Green");
});

.Button {
  font-weight: bold;
  font-size: 13px;
  background: #0096db;
  text-align: center;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
  padding: 15px;
  color: #fff;
  position: static;
  float: right;
  min-width: 25%;
  max-width: 40%;
}

.Button.Green {
  background: #64B448;
  font-weight: bold;
  font-size: 13px;
  text-align: center;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
  padding: 15px;
  color: #fff;
  position: static;
  float: right;
  min-width: 25%;
  max-width: 40%;
}

.productset1 {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 2fr));
  grid-template-rows: repeat(auto-fit, minmax(10px, 1fr));
  grid-gap: 5px;
}
.productset2 {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 2fr));
  grid-template-rows: repeat(auto-fit, minmax(10px, 1fr));
  grid-gap: 5px;
}

<h1>Product Set 1</h1>

<div class="productset1">

Or, as David Thomas pointed out, get it without script with radio inputs:

Example:

.Button {
  font-weight: bold;
  font-size: 13px;
  background: #0096db;
  text-align: center;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
  padding: 15px;
  color: #fff;
  position: static;
  float: right;
  min-width: 25%;
  max-width: 40%;
}

input[type=radio] {
  display: none;
}

input[type=radio]:checked + .Button {
  background: #64B448;
  font-weight: bold;
  font-size: 13px;
  text-align: center;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
  padding: 15px;
  color: #fff;
  position: static;
  float: right;
  min-width: 25%;
  max-width: 40%;
}

.productset1 {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 2fr));
  grid-template-rows: repeat(auto-fit, minmax(10px, 1fr));
  grid-gap: 5px;
}
.productset2 {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(200px, 2fr));
  grid-template-rows: repeat(auto-fit, minmax(10px, 1fr));
  grid-gap: 5px;
}

<h1>Product Set 1</h1>

<div class="productset1">
<input id="btn1" type="radio" name="set1">
<label for="btn1" class="Button">Button 1</label>
<input id="btn2" type="radio" name="set1">
<label for="btn2" class="Button">Button 2</label>
</div>

<h1>Product Set 2</h1>

<div class="productset2">
<input id="btn3" type="radio" name="set2">
<label for="btn3" class="Button">Button 3</label>
<input id="btn4" type="radio" name="set2">
<label for="btn4" class="Button">Button 4</label>
</div>

...but it does increase the complexity of the markup. :-)
