I would like to know how to add input text box to the select dropdown and use it as search filter in javascript.
<select class="form-control">
<option value="trans">Trans</option>
<option value="fund">Fund</option>
<option value="insta">Insta</option>
</select>
You can try <datalist>:
The HTML
<datalist>element contains a set of elements that represent the values available for other controls.
<input list="select" name="select">
<datalist class="form-control" id="select">
<option value="Trans"/>
<option value="Fund"/>
<option value="Insta"/>
</datalist>
Here is a sample from w3 schools:
/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
function filterFunction() {
var input, filter, ul, li, a, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
div = document.getElementById("myDropdown");
a = div.getElementsByTagName("a");
for (i = 0; i < a.length; i++) {
txtValue = a[i].textContent || a[i].innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
a[i].style.display = "";
} else {
a[i].style.display = "none";
}
}
} /* Dropdown Button */
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
/* Dropdown button on hover & focus */
.dropbtn:hover, .dropbtn:focus {
background-color: #3e8e41;
}
/* The search field */
#myInput {
border-box: box-sizing;
background-image: url('searchicon.png');
background-position: 14px 12px;
background-repeat: no-repeat;
font-size: 16px;
padding: 14px 20px 12px 45px;
border: none;
border-bottom: 1px solid #ddd;
}
/* The search field when it gets focus/clicked on */
#myInput:focus {outline: 3px solid #ddd;}
/* The container <div> - needed to position the dropdown content */
.dropdown {
position: relative;
display: inline-block;
}
/* Dropdown Content (Hidden by Default) */
.dropdown-content {
display: none;
position: absolute;
background-color: #f6f6f6;
min-width: 230px;
border: 1px solid #ddd;
z-index: 1;
}
/* Links inside the dropdown */
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #f1f1f1}
/* Show the dropdown menu (use JS to add this class to the .dropdown-content container when the user clicks on the dropdown button) */
.show {display:block;}<div class="dropdown">
<button onclick="myFunction()" class="dropbtn">Dropdown</button>
<div id="myDropdown" class="dropdown-content">
<input type="text" placeholder="Search.." id="myInput" onkeyup="filterFunction()">

</div>
</div> Here is a simple solution using select2
Even the items get filtered
$(document).ready(function() {
$('.js-example-basic-single').select2();
});<select class="js-example-basic-single" name="state">
<option value="AL">Alabama</option>
...
<option value="WY">Wyoming</option>
