title: Rails 7 + ImportMaps/whatever + TailwindCSS + JS = Boggled
body: <p>First, I'm much more of a Rails back end person. The JS world today scares me. I know this is a super basic question, but I've racked my brain for a solid couple days trying to <a href="https://tailwindui.com/documentation#using-html-and-your-own-js" rel="nofollow noreferrer">figure</a>, <a href="https://stackoverflow.com/questions/70488810/rails-7-tailwindcss-js">this</a> <a href="https://gorails.com/forum/installing-tailwind-with-rails-7" rel="nofollow noreferrer">out</a>. I don't know why I can't put a CDN link somewhere in my HTML and get all the JS I need. Those were the good ol' days...</p>
  <p>Anyway, I have a nearly fresh Rails 7 app that uses import-maps (do they all?) and I'm trying to get a dropdown &quot;component&quot; from <a href="https://tailwindui.com/preview" rel="nofollow noreferrer">https://tailwindui.com/preview</a> (the first navbar from that page) working. It starts popped open, no hover effects, and is unable to close. My goal is to use more of those components, but all the docs I read seem to leave me thinking there's a missing piece I'm not understanding.</p>
  <p><strong>Gemfile</strong> contains <code>gem &quot;tailwindcss-rails&quot;, &quot;~&gt; 2.0&quot; # github: &quot;rails/tailwindcss-rails&quot;</code></p>
  <p><strong>app/assets/stylesheets/application.tailwind.css</strong>:</p>
  <pre><code>@tailwind base;
  @tailwind components;

  <p><strong>app/assets/javascript/application.js</strong></p>
  <pre><code>// Configure your import map in config/importmap.rb. Read more: https://github.com/rails/importmap-rails

  </code></pre>
  <p><strong>config/tailwind.config.js</strong></p>
  <pre><code>// const defaultTheme = require('tailwindcss/defaultTheme')
  
  // module.exports = {
  //   content: [
  //     './app/helpers/**/*.rb',
  //     './app/javascript/**/*.js',
  //     './app/views/**/*'
  //   ],
  //   theme: {
  //     extend: {
  //       fontFamily: {
  //         sans: ['Inter var', ...defaultTheme.fontFamily.sans],
  //       },
  //     },
  //   },
  //   plugins: [
  //     require('@tailwindcss/forms'),
  //     require('@tailwindcss/aspect-ratio'),
  //     require('@tailwindcss/typography'),
  //   ]
  // }
  </code></pre>
  <p>What else do I need to put where to get this working? Thank you kindly for filling in the missing pieces in my brain.</p>
