Materialize::Form

This is a generator gem for SimpleForm to make it works with MaterializeCSS.

There is an example application available on Heroku that demonstrate various features of Materialize::Form. You can view here: http://materialize-form.herokuapp.com/. To see the Source Code

Haven’t install SimpleForm and Materialize SASS? Please follow this instruction:

Add this line to your application’s Gemfile:

gem 'simple_form'
gem 'materialize-sass'

$ bundle install
$ rails generate simple_form:install

Require Materialize javascripts in app/assets/javascripts/application.js:

//= require jquery
//= require materialize-sprockets

Import Materialize styles in app/assets/stylesheets/application.scss:

@import "materialize";

NOTE: If you have just generated a new Rails application, it may come with a .css file instead. If this file exists, it will be served instead of Sass, so remove it.

$ rm app/assets/stylesheets/application.css

Installation

Step 1:

Add this line to your application’s Gemfile:

gem 'materialize-form'

Step 2:

Run the bundler and restart your server to make the files available through the pipeline and run the generator

$ bundle install
$ rails generate simple_form:materialize:install

Step 3:

Import Materialize Form javascript in app/assets/javascripts/application.js:

//= require materialize-form

  .row
    = f.input :first_name, wrapper_html: { class: 'm6 s12' }
    = f.input :last_name, wrapper_html: { class: 'm6 s12' }

  = f.button :submit

Selectbox

= f.association :country, include_blank: 'What are your country?', wrapper_html: { class: 'm6 s12' }
