This AngularJS code helps you to create a search filter dropdown. The application uses AngularJS and demonstrates how to implement a search filter dropdown functionality. It stores data in an array and allows users to filter the list using select dropdown. The code showcases how to bind the data to the HTML view and apply the desired sorting order.

Whether you’re building a product catalog or a data-driven application, this code snippet provides a useful reference for implementing search filter dropdowns in your AngularJS projects.

How to Create Search Filter Dropdown In Angular

First of all, load the -prefix-free JS by adding the following CDN link into the head tag of your webpage.

<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>

Create the HTML structure for search/filter interface as follows:

<div id="notebooks" ng-app="notebooks" ng-controller="NotebookListCtrl">
  <input type="text" id="query" ng-model="query"/>
  <select ng-model="orderList">
    <option value="name">By name</option>
    <option value="-age">Newest</option>
    <option value="age">Oldest</option>
  </select>
  <ul id="notebook_ul">
    <li ng-repeat="notebook in notebooks | filter:query | orderBy: orderList">
      name: {{notebook.name}}<br/>
      procesor: {{notebook.procesor}}<br/>
      <div class="right top">{{notebook.age}}</div>
    </li>
  </ul>
  <span>Number of notebooks: {{notebooks.length}}</span>
</div>

After that, style the filter interfcae using the following CSS styles:

html, body {
  height: 100%;
}

body {
  font-family: helvetica;
  font-weight: 100;
  font-size: 14px;
  margin: 0 auto;
}

.cd__main{
    background: #FFFFBB !important;
}

.right {
  float: right;
  position: relative;
  top: 6px;
}

.top {
  margin-top: -30px;
}

#notebooks {
  background: whitesmoke;
  position: relative;
  margin-top: 35px;
  width: 350px;
  padding: 15px;
  border: 1px solid rgba(0, 0, 0, 0.2);
  border-radius: 5px;
  box-shadow: inset 1px 1px 0 white;
  max-height: 450px;
}

ul {
  margin: 0 auto;
  padding: 0;
  max-height: 390px;
  overflow-y: auto;
  border: 1px solid rgba(0, 0, 0, 0.1);
  padding: 5px 5px 0 5px;
  border-left: none;
  border-right: none;
}

li {
  list-style: none;
  background-color: rgba(0, 0, 0, 0.05);
  background-image: 
    linear-gradient(
      90deg,
      #FFD32E 10px,
      #EEE 10px,
      #EEE 11px,
      transparent 11px);
  padding: 10px 15px 10px 25px;
  border: 1px solid #CCC;
  box-shadow: inset 1px 1px 0 rgba(255, 255, 255, 0.5);
  margin-bottom: 5px;
  width: 100%;
  box-sizing: border-box;
  cursor: pointer;
  border-radius: 3px;
}

#query {
  width: 100%;
  box-sizing: border-box;
  font-size: 19px;
  padding: 5px;
  font-family: calibri light;
  margin-bottom: 10px;
  border: 1px solid rgba(0, 0, 0, 0.2);
  border-radius: 3px;
  box-shadow: inset 1px 1px 0 rgba(0, 0, 0, 0.1);
}

#notebooks span {
  display: block;
  position: absolute;
  background: #FFD32E;
  bottom: -35px;
  left: -1px;
  width: 360px;
  border-radius: 0 0 5px 5px;
  border: 1px solid rgba(0, 0, 0, 0.1);
  padding: 10px;
  border-top: 1px solid rgba(0, 0, 0, 0.1);
  box-shadow: inset 1px 1px rgba(255, 255, 255, 0.5);
}

#notebooks select {
  width: 120px;
  margin-left: 230px;
  margin-top: -45px;
  border-radius: 0 3px 3px 0;
  border: 1px solid rgba(0, 0, 0, 0.2);
  border-left: 1px solid rgba(0, 0, 0, 0.1);
  position: absolute;
  padding: 7.5px;
  box-shadow: inset 0 1px 0 rgba(0, 0, 0, 0.1);
}

#notebooks select:focus, #query:focus {
  border: 1px solid #FFD32E;
  box-shadow: 0 0 10px rgba(255, 255, 0, 0.1);
  outline: none;
}

Now, load the AngularJS by adding the following CDN link before closing the body tag:

<script src='https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js'></script>

Finally, add the following JavaScript function to your project to activate the search filter dropdown:

var notebooks = angular.module('notebooks', []);

notebooks.controller('NotebookListCtrl', function($scope) {
  $scope.notebooks = [
    {"name": "Lenovo",
     "procesor": "Intel i5",
     "age": 2011},
    {"name": "Toshiba",
     "procesor": "Intel i7",
     "age": 2010},
    {"name": "Toshiba",
     "procesor": "Intel core 2 duo",
     "age": 2008},
    {"name": "HP",
     "procesor": "Intel core 2 duo",
     "age": 2012},
    {"name": "Acer",
     "procesor": "AMD",
     "age": 2006},
    {"name": "Lenovo",
     "procesor": "Intel i5",
     "age": 2009},
    {"name": "Toshiba",
     "procesor": "Intel i7",
     "age": 2008},
    {"name": "Lenovo",
     "procesor": "Intel i5",
     "age": 2011},
    {"name": "Toshiba",
     "procesor": "Intel i7",
     "age": 2010},
    {"name": "Toshiba",
     "procesor": "Intel core 2 duo",
     "age": 2008},
    {"name": "HP",
     "procesor": "Intel core 2 duo",
     "age": 2012},
    {"name": "Acer",
     "procesor": "AMD",
     "age": 2006},
    {"name": "Lenovo",
     "procesor": "Intel i5",
     "age": 2009},
    {"name": "Toshiba",
     "procesor": "Intel i7",
     "age": 2008},
    {"name": "Lenovo",
     "procesor": "Intel i5",
     "age": 2011},
    {"name": "Toshiba",
     "procesor": "Intel i7",
     "age": 2010},
    {"name": "Toshiba",
     "procesor": "Intel core 2 duo",
     "age": 2008},
    {"name": "HP",
     "procesor": "Intel core 2 duo",
     "age": 2012},
    {"name": "Acer",
     "procesor": "AMD",
     "age": 2006},
    {"name": "Lenovo",
     "procesor": "Intel i5",
     "age": 2009},
    {"name": "Toshiba",
     "procesor": "Intel i7",
     "age": 2008}
  ];
  $scope.orderList = "name";
});
