AngularJS Question

Set Custom Heigh Angular Material Autocomplete Dropdown


I am doing a custom autocomplete with Angular Material and I would like to set the height of the autocomplete dropdown results box to something bigger.


To achieve this, I made a research and concluded that Angular Material does not support this, and that this issue will only be addressed in Angular Material 2 (to be released for AngularJS2):

After reading, I realized that some people found a way around this limitation forcing the CSS (Angular Material Design Layout custom sizes), but not matter what I try I can't see to make any of their suggestions work.


My sample app is composed of an
, an
file, and the
file with a mockData.json file.

Following are the
files. Since I am hosting this example in Cloud9 if the server is ON you can see it run live !

/*global angular*/

"use strict";
angular.module('MyApp', ['ngMaterial', 'ngMessages', 'material.svgAssetsCache', 'ngMdIcons']).controller('DemoCtrl', DemoCtrl);

function DemoCtrl($q, $log, $http) {

this.searchText = null;

this.querySearch = function(query) {
let serverUrl = '//custom-material-autocomplete-fl4m3ph03n1x.c9users.io/getClients';
let deferred = $q.defer();
method: 'GET',
url: serverUrl,
params: {
word: query

}).then(function successCallback(response) {
}, function errorCallback(response) {

return deferred.promise;

this.searchTextChange = function(text) {
$log.info('Text changed to ' + text);

this.selectedItemChange = function(item) {
$log.info('Item changed to ' + JSON.stringify(item));

.autocompletedemoCustomTemplate .autocomplete-custom-template li {
border-bottom: 1px solid #ccc;
height: auto;
padding-top: 8px;
padding-bottom: 8px;
white-space: normal;

.autocompletedemoCustomTemplate .autocomplete-custom-template li:last-child {
border-bottom-width: 0;

.autocompletedemoCustomTemplate .autocomplete-custom-template .item-title,
.autocompletedemoCustomTemplate .autocomplete-custom-template .item-metadata {
display: block;
line-height: 2;

.autocompletedemoCustomTemplate .autocomplete-custom-template .item-title md-icon {
height: 18px;
width: 18px;

<html lang="en">

<meta name="viewport" content="width=device-width, initial-scale=1">

<div ng-controller="DemoCtrl as ctrl" layout="column" ng-cloak="" class="autocompletedemoCustomTemplate" ng-app="MyApp">

md-item-text="item.name" md-min-length="0" placeholder="Pick an Angular repository" md-menu-class="autocomplete-custom-template">

<span class="item-title">
<strong>Company name:</strong> {{item.Company_Name}}

How can I make my dropdown box for the results bigger?

Answer Source


After much experimentation and reading, I finally found a workaround on how to do it.

My solution is not really a solution to the problem, but more of a hack. The truth is that there is no official support for this, and there will never be, at least in Angular Material 1, which has now been deprecated in order to make Angular Material 2, and has lost official support.


Thus my workaround focuses on one suggestion found in github, and it effectively overrides the default CSS:

.md-virtual-repeat-container.md-autocomplete-suggestions-container {
    height: 24vh;
    min-height: 12vh;
    max-height: 24vh !important;

Explanation & Analysis

This code overrides the default CSS by using !important and setting custom heights. In this case I am using the vh measurement, but you can use the px or any other.

This workaround will work fine if you only have one autocomplete with a dropdownbox, or if all the autocomplete with dropdownboxes you have are equal.

If however, you have two autocompletes different from each other, you will start fighting with your own code because of the override (which will affect all autocompletes).


This is, in the end, not a perfect solution, but as long as you don't go too much into autocomplete, it should be fine.

I hope this can help someone in the future!
