<div class="select" id="1">Egg</div>

<div class="select" id="3">apple</div>
<div class="select" id="4">egg</div>
<div class="select" id="5">apple</div>
<div class="select" id="6">egg</div>
</body>
<script>
$('.select').click(function(e){
var $et = $(e.target);
if ($et.hasClass('fill')) {
$et.removeClass('fill');
} else {
if ($('.fill').length < 3) {
$et.addClass('fill');
$et.blur();
}
}
});
</script>

Consider the following.
$(function() {
$('.select').click(function(e) {
var $et = $(this);
if ($et.hasClass('fill')) {
$et.toggleClass('fill');
} else if ($et.parent().find(".fill").length < 3) {
$et.toggleClass('fill');
}
return false;
});
});.select {
border: 1px solid blue;
height: 25px;
margin-bottom: 5px;
}
.fill {
background-color: red;
}<script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" crossorigin="anonymous"></script>
<div class="wrapper">
<div class="select" id="1">Egg</div>
<div class="select" id="2">mango</div>
<div class="select" id="3">apple</div>
<div class="select" id="4">egg</div>
<div class="select" id="5">apple</div>
<div class="select" id="6">egg</div>
</div>Adding a wrapper allows for better reference to the parent. You can then check how many .fill elements there are inside the wrapper. Now you can conditionally remove or add fill class.
