If you want to use materialize JS functionalities like dropdown, sidenavs, etc. This is the process that worked for me.

You can choose one of two paths. The first path involves using the current materialize-sass gem and you'll need follow the four steps. For the second path you'll only need to go up to step three but you'll be using my fork on Github of the gem in your Gemfile

Use the original gem (Follow all the steps)

gem 'materialize-sass'

Use my forked version of the gem (Follow up to step three)

gem "materialize-sass", git: "https://github.com/Joaquinb2000/materialize-sass-rails-7.git"

After installing one of the gems be sure to follow steps 3 and 4 from Korak's answer to add the materialize stylesheets to your app.

Step 1. Add this line at the end of your config/initializers/assets.rb

Rails.application.config.assets.precompile += %w( materialize.js )

Step 2. Add these two lines after everything in config/importmap.rb

pin "jquery", to: "https://code.jquery.com/jquery-3.6.3.min.js"
pin "materialize", to: "materialize.js"

Step 3. In your app/javascript/application.js put these two at the end

import "jquery"
import "materialize"

After that, remember to add the correspondent code to activate the effects you want. For example, if you wanted to activate dropdowns you'd add the following line after the 'import "materialize"':

$(".dropdown-trigger").dropdown();

Step 4. Find the install path for your gems. In my case I use rbenv in ubuntu wsl, so you'd find it in your home directory "~/.rbenv" or "/home/#{your_username}/.rbenv"

Once you find the location of the gem and you're inside its folder go to "assets/javascripts" and edit materialize.js with the code editor you like best. Go over to line 1509 and replace the following line:

p = $jscomp.global;e = e.split(".");for (m = 0; m < e.length - 1; m++) {

With:

let p = $jscomp.global;e = e.split("."); if(!p) p = new Array();for (m = 0; m < e.length - 1; m++) {
