How to reset multiple select to its first value in Jquery

I have a select which contains options, I want to be able to resent each of the select to its first value onclick
$('.reset').on('click', function() {
$('food option:first').prop('selected', true);
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="box">
<select class="food">
<option value="" selected disabled>Select Food</option>
<option value="rice">Rice</option>
<option value="garri">Garri</option>
</select>
<input type="text" class="showfood">
<button class="reset">Reset Select</button>
</div>
<div class="box">
<select class="food">
<option value="" selected disabled>Select Food</option>
<option value="beans">Beans</option>
<option value="pear">pear</option>
</select>
<input type="text" class="showfood">
<button class="reset">Reset Select</button>
</div>
However, what this does is reset only the first select.

Your logic to reset is correct. The issue you have is that you need to find only the option related to the select within the same container as the clicked button. To achieve that you can use closest() and find(), like this:
$('.reset').on('click', function() {
$(this).closest('.box').find('.food option:first').prop('selected', true);
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="box">
<select class="food">
<option value="" selected disabled>Select Food</option>
<option value="rice">Rice</option>
<option value="garri">Garri</option>
</select>
<input type="text" class="showfood">
<button class="reset">Reset Select</button>
</div>
<div class="box">
<select class="food">
<option value="" selected disabled>Select Food</option>
<option value="beans">Beans</option>
<option value="pear">pear</option>
</select>
<input type="text" class="showfood">
<button class="reset" type="button">Reset Select</button>
</div>

Parent <div> hides when I click it

I have a input-field, and when I click it a <div> will be shown.
But for some reason when I click on the <div>, it hides, and I can't seem to find the issue.
JSfiddle
$('#searchid').blur(function() {
if ($(this).val() != "") {
$("#drope_box").show();
} else {
$("#drope_box").hide();
}
});
$('#searchid').focus(function() {
$("#drope_box").show();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="banner_search_inner_box_search">
<input type="text" name="search" class="search" id="searchid" onkeyup="getshows();" value="" placeholder="Enter a City,Locality" autocomplete="off">
<div id="result"></div>
</div>
<div id="drope_box" style="display:none;">
<div class="banner_search_type">
<select id="property_type" name="property_type">
<option value="All">All</option>
<option value="Apartment">Apartment</option>
<option value="Plot">Plot</option>
</select>
</div>
<div class="banner_search_price_min">
<select name="price_min" class="search_list" id="price_min">
<option value="">Price Min</option>
<option value="100000">1 lac</option>
<option value="1000000">10 lacs</option>
</select>
</div>
<div class="banner_search_price_max">
<select name="price_max" id="price_max">
<option value="">Price Max</option>
<option value="100000">1 lac</option>
<option value="1000000">10 lacs</option>
</select>
</div>
</div>

This is because you're hiding the <div> when you lose focus on the input and there is no value.
In your blur handler, if the input is empty (as when you first click it), it will hide the dropdown when the input loses focus.

check this I hope that this answered what you have asked for...
$('#searchid').blur(function() {
if($(this).val() != ""){
$("#drope_box").hide();
}
else{
$("#drope_box").show();
}
});
$('#searchid').focus(function() {
$("#drope_box").show();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="banner_search_inner_box_search">
<input type="text" name="search" class="search" id="searchid" onkeyup="getshows();" value="" placeholder="Enter a City,Locality" autocomplete="off">
<div id="result"></div>
</div>
<div id="drope_box" style="display:none;">
<div class="banner_search_type">
<select id="property_type" name="property_type">
<option value="All">All</option>
<option value="Apartment">Apartment</option>
<option value="Plot">Plot</option>
</select>
</div>
<div class="banner_search_price_min">
<select name="price_min" class="search_list" id="price_min">
<option value="">Price Min</option>
<option value="100000">1 lac</option>
<option value="1000000">10 lacs</option>
</select>
</div>
<div class="banner_search_price_max">
<select name="price_max" id="price_max">
<option value="">Price Max</option>
<option value="100000">1 lac</option>
<option value="1000000">10 lacs</option>
</select>
</div>
</div>

Display a required text input when Other is selected

I need to add a text input that displayed only when the other is selected. And make this input required if it is shown. One thing more, I need to enter that input to the same table in the database. Can anyone help? Please!
<form action="" method="post">
<div class="row">`enter code here`
<div class="col-sm-8 col-sm-offs et-2">
<select class="form-control" name="country" id="country" required>
<option value="">Please select your country</option>
<option value="A">Country A</option>
<option value="B">Country B</option>
<option value="C">Country C</option>
<option value="Other">Other</option>
</select>
<button type="submit" class="btn btn-gpsingh">Next</a>
</div>
</div>
</form>

Try this
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" method="post">
<div class="row">
<div class="col-sm-8 col-sm-offs et-2">
<select class="form-control" name="country" id="country" required >
<option value="">Please select your country</option>
<option value="A">Country A</option>
<option value="B">Country B</option>
<option value="C">Country C</option>
<option value="Other">Other</option>
</select>
<input type ="text" id="country_other" style="display:none">
<button type="submit" class="btn btn-gpsingh">Next</a>
</div>
</div>
</form>
<script>
$("#country").change(function(){
var value = this.value;
if(value =='Other')
{
$("#country_other").show();
$("#country_other").prop('required',true);
$("#country_other").val('');
}
else
{
$("#country_other").hide();
$("#country_other").prop('required',false);
$("#country_other").val('');
}
});
</script>

Input's placeholder won't change from <select>

So basically what I'm trying to achieve is to make the placeholder of the inputs change when I change the select. The first input successfully changes, but that doesn't seem to be the same with the second input. Below is the code that I am using:
function onChange(fromOrTo) {
if (fromOrTo = 'from') {
document.getElementById("from").placeholder = document.getElementById("selectFrom").value;
} else if (fromOrTo = 'to') {
document.getElementById("to").placeholder = document.getElementById("selectTo").value;
}
}
<body>
<div id="sect">
<section>
<select onchange="onChange('from')" id="selectFrom">
<option value="Celcius">Celcius</option>
<option value="Farenheit">Farenheit</option>
<option value="Kelvin">Kelvin</option>
<option value="Reamur">Reamur</option>
</select>
<span class="toText">to</span>
<select onchange="onChange('to')" id="selectTo">
<option value="Celcius">Celcius</option>
<option value="Farenheit">Farenheit</option>
<option value="Kelvin">Kelvin</option>
<option value="Reamur">Reamur</option>
</select>
</section>
<section>
<input type="text" id="from">
<span id="toText">to</span>
<input type="text" id="to">
</section>
</div>
</body>

You just need to compare with === instead of =
function onChange(fromOrTo) {
if (fromOrTo === 'from') {
document.getElementById("from").placeholder = document.getElementById("selectFrom").value;
} else if (fromOrTo === 'to') {
document.getElementById("to").placeholder = document.getElementById("selectTo").value;
}
}
<body>
<div id="sect">
<section>
<select onchange="onChange('from')" id="selectFrom">
<option value="Celcius">Celcius</option>
<option value="Farenheit">Farenheit</option>
<option value="Kelvin">Kelvin</option>
<option value="Reamur">Reamur</option>
</select>
<span class="toText">to</span>
<select onchange="onChange('to')" id="selectTo">
<option value="Celcius">Celcius</option>
<option value="Farenheit">Farenheit</option>
<option value="Kelvin">Kelvin</option>
<option value="Reamur">Reamur</option>
</select>
</section>
<section>
<input type="text" id="from">
<span id="toText">to</span>
<input type="text" id="to">
</section>
</div>
</body>

You only have one equals sign in each of your if conditionals. This assigns to the variable rather than compares it. Switching to two equals signs (or three to avoid type coercison) will resolve this problem:
function onChange(fromOrTo) {
if (fromOrTo === 'from') {
document.getElementById("from").placeholder = document.getElementById("selectFrom").value;
} else if (fromOrTo === 'to') {
document.getElementById("to").placeholder = document.getElementById("selectTo").value;
}
}
<body>
<div id="sect">
<section>
<select onchange="onChange('from')" id="selectFrom">
<option value="Celcius">Celcius</option>
<option value="Farenheit">Farenheit</option>
<option value="Kelvin">Kelvin</option>
<option value="Reamur">Reamur</option>
</select>
<span class="toText">to</span>
<select onchange="onChange('to')" id="selectTo">
<option value="Celcius">Celcius</option>
<option value="Farenheit">Farenheit</option>
<option value="Kelvin">Kelvin</option>
<option value="Reamur">Reamur</option>
</select>
</section>
<section>
<input type="text" id="from">

How to do show and hide the form field based on the selection???

You need to use $('div').clone().html(). See the below working solution and it has some changes in html.
$(document).ready(function() {
$('#hidden-div').hide();
$("#select_btn").change(function() {
toggleFields();
});
});
function toggleFields() {
var selectVal = $("#select_btn").val();
if (selectVal <= 5) {
$hiddenHtml = $('#hidden-div').clone().html();
$("#parentPermission").html('');
for (var i = 0; i < selectVal; i++) {
$("#parentPermission").append($hiddenHtml);
}
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form method="POST">
<p>Name:
<input type="text" name="player_name" />
</p>
<p>Mobile:
<input type="text" name="mobile" />
</p>
<p>Email:
<input type="text" name="player_email" />
</p>
<p>No of Referrer:
<select id="select_btn" name="age">
<option value="0">--Select--</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
<div id="hidden-div">
<p>Name:
<input type="text" name="reference_name" />
</p>
<p>Mobile:
<input type="text" name="reference_mobile" />
</p>
<p>Email:
<input type="text" name="reference_email" />
</p>
<p>City:
<select id="city" name="City">
<option value="0">--Select City--</option>
<option value="Mumbai">Mumbai</option>
<option value="Chennai">Chennai</option>
<option value="Delhi">Delhi</option>
<option value="Jammu">Jammu</option>
<option value="Ooty">Ooty</option>
</select>
</p>
<p>Course:
<select id="course" name="Course">
<option value="B.com">B.com</option>
<option value="B.A">B.A</option>
<option value="MBA">MBA</option>
<option value="B.Sc">B.Sc</option>
<option value="BCA">BCA</option>
</select>
</p>
<p>You must have parental permission before you can play.</p>
</div>
<div id="parentPermission">
</div>
<p align="center">
<input type="submit" value="Join!" />
</p>
</form>

This could be realized via .clone() and editing ids / names of the cloned objects. Alternatively: Your #select_btn already has number values for it, use them in a foreach to directly modify the html() output.

$(document).ready(function() {
$('#hidden-div').hide();
$("#select_btn").change(function() {
toggleFields();
});
});
function toggleFields() {
var selectVal = $("#select_btn").val();
if (selectVal <= 5) {
$hiddenHtml = $('#hidden-div').clone().html();
$("#parentPermission").html('');
for (var i = 0; i < selectVal; i++) {
$("#parentPermission").append($hiddenHtml);
}
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form method="POST">
<p>Name:
<input type="text" name="player_name" />
</p>
<p>Mobile:
<input type="text" name="mobile" />
</p>
<p>Email:
<input type="text" name="player_email" />
</p>
<p>No of Referrer:
<select id="select_btn" name="age">
<option value="0">--Select--</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>

</p>

</p>
<p>Email:

</p>
<p>City:

<option value="0">--Select City--</option>
<option value="Mumbai">Mumbai</option>
