Introduction

This package was introduced to collect and fix all common known issues of Materialize library without removing any features, but rather making them work as expected.

Known Issues

Currently there are few commonly known issues caused by the Materialize:

1. Select element is misbehaving on iOS

On iOS, when clicking one select dropdown option, other one is being selected. This issue is caused by the dropdown animation. This package will fix the bug while keeping the dropdown animation.

2. Lighthouse warning for Select element

Select trigger input causes a Lighthouse warning for not having a label or placeholder:

Form elements do not have associated labels

This package will dynamically add a placeholder depending on a selected option value.

3. Input label is not marked as active on autocompletion

When an input is autocompleted by the browser (i.e "username" and "password" fields), the onchange event for the input is not being triggered and that causes the label element to cover the input even tho it is autocompleted and filled in by the browser. This package will listen to onautocomplete event and assign .active class to the label forcing it to move up.

4. Materialize is adding non-passive event listeners

This is not fixed by this package. Use passive-events-support package to resolve it.

Installation

yarn add materialize-css-helper

Usage

By default, this package will automatically resolve all the in the Known Issues section mentioned issues. It's script will automatically be executed upon DOMContentLoaded.

Make sure this package is loaded after the Materialize script.

// With JS
import 'materialize-css-helper'
// to pass the custom configuration
import { initMaterializeHelper } from 'materialize-css-helper/src/utils'
initMaterializeHelper({/*...*/})

<!-- With HTML -->
<script>
  // if undefined will apply the default configuration
  window.materializeHelper = {/*...*/}
</script>
