TailwindCSS Stimulus Components

Check out the demo

This is a set of components (Tabs, Modals, Dropdowns, etc) for TailwindCSS that uses StimulusJS controllers.

The goal is to make using TailwindCSS as easy as Bootstrap when it comes to adding Javascript components.

Install

This assumes that StimulusJS is already installed.

Add the tailwindcss-stimulus-components module:

$ yarn add tailwindcss-stimulus-components

or

$ npm install tailwindcss-stimulus-components

or use directly from unpkg:

<script src="https://unpkg.com/tailwindcss-stimulus-components/dist/tailwindcss-stimulus-components.js"></script>

Basic Usage

First, you'll want to initialize StimulusJS and then you can import all the TailwindCSS components.

// Start StimulusJS
import { Application } from "stimulus"
import { definitionsFromContext } from "stimulus/webpack-helpers"

const application = Application.start();
const context = require.context("controllers", true, /.js$/);
application.load(definitionsFromContext(context));

// Import and register all TailwindCSS Components
import { Dropdown, Modal, Tabs, Popover, Toggle } from "tailwindcss-stimulus-components"
application.register('dropdown', Dropdown)
application.register('modal', Modal)
application.register('tabs', Tabs)
application.register('popover', Popover)
application.register('toggle', Toggle)

This will start StimulusJS and load any controllers that you have locally and then register the TailwindCSS components.

Alternatively, you can use the import lines below to import the individual features you need.

Dropdowns

import { Dropdown } from "tailwindcss-stimulus-components"
application.register('dropdown', Dropdown)

<div class="inline-block text-sm px-4 py-2 leading-none rounded no-underline text-gray hover:text-gray-900 hover:bg-white mt-4 lg:mt-0">
  <div class="relative" data-controller="dropdown">
    <div data-action="click->dropdown#toggle click@window->dropdown#hide" role="button" class="inline-block select-none">
      <span class="appearance-none flex items-center inline-block text-gray-700">
        <% if current_user %>
          <%= image_tag avatar_url_for(current_user), class: "rounded-full h-8 w-8 align-middle" %>
        <% end %>
        <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 20 20" class="h-4 w-4"><path d="M9.293 12.95l.707.707L15.657 8l-1.414-1.414L10 10.828 5.757 6.586 4.343 8z"></path></svg>
      </span>
    </div>
    <div data-target="dropdown.menu" class="absolute right-0 mt-2 hidden">
      <div class="bg-white shadow rounded border overflow-hidden">
          <%= link_to 'Profile',  edit_user_registration_path, class: 'no-underline block pl-8 py-3 text-gray-900 bg-white hover:bg-gray-300 whitespace-no-wrap' %>
          <%= link_to 'Password', password_path, class: 'no-underline block px-8 py-3 text-gray-900 bg-white  hover:bg-gray-300 whitespace-no-wrap' %>
          <%= link_to 'Accounts', user_connected_accounts_path, class: 'no-underline block px-8 py-3 text-gray-900 bg-white  hover:bg-gray-300 whitespace-no-wrap' %>
          <%= link_to 'Billing',  subscription_path, class: 'no-underline block px-8 py-3 text-gray-900 bg-white  hover:bg-gray-300 whitespace-no-wrap' %>
          <%= link_to 'Sign Out', destroy_user_session_path, method: :delete, class: 'no-underline block px-8 py-3 border-t text-gray-900 bg-white  hover:bg-gray-300 whitespace-no-wrap' %>
      </div>
    </div>
  </div>
</div>

Dropdowns are set up to toggle if you click on the dropdown button. It will also close if you click anywhere outside of the dropdown. This is done using a window click event to check if the user clicked outside the dropdown.

Modals

import { Modal } from "tailwindcss-stimulus-components"
application.register('modal', Modal)

<div data-controller="modal" data-modal-allow-background-close="false">
  <a href="#" data-action="click->modal#open" class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-3 px-6 rounded">
    <span>Open Modal</span>
  </a>

  <!-- Modal Container -->
  <div data-target="modal.container" data-action="click->modal#closeBackground keyup@window->modal#closeWithKeyboard" class="hidden animated fadeIn fixed inset-0 overflow-y-auto flex items-center justify-center" style="z-index: 9999;">
    <!-- Modal Inner Container -->
    <div class="max-h-screen w-full max-w-lg relative">
      <!-- Modal Card -->
      <div class="m-1 bg-white rounded shadow">
        <div class="p-8">
          <h2 class="text-xl mb-4">Large Modal Content</h2>
          <p class="mb-4">This is an example modal dialog box.</p>

          <div class="flex justify-end items-center flex-wrap mt-6">
            <button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded" data-action="click->modal#close">Close</button>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

data-modal-allow-background-close may be set to false to disable closing the modal when a user clicks on the background. Defaults to true

data-modal-disable-backdrop may be set to true to disable adding the modal's dark transparent backdrop. This is useful if you want to make a fullscreen modal.

Tabs

import { Tabs } from "tailwindcss-stimulus-components"
application.register('tabs', Tabs)

<div data-controller="tabs" data-tabs-active-tab="-mb-px border-l border-t border-r rounded-t">
  <ul class="list-reset flex border-b">
    <li class="-mb-px mr-1" data-target="tabs.tab" data-action="click->tabs#change">
      <a class="bg-white inline-block py-2 px-4 text-blue-500 hover:text-blue-700 font-semibold no-underline" href="#">Active</a>
    </li>
    <li class="mr-1" data-target="tabs.tab" data-action="click->tabs#change">
      <a class="bg-white inline-block py-2 px-4 text-blue-500 hover:text-blue-700 font-semibold no-underline" href="#">Tab</a>
    </li>
    <li class="mr-1" data-target="tabs.tab" data-action="click->tabs#change">
      <a class="bg-white inline-block py-2 px-4 text-blue-500 hover:text-blue-700 font-semibold no-underline" href="#">Tab</a>
    </li>
    <li class="mr-1">
      <a class="bg-white inline-block py-2 px-4 text-gray-300 font-semibold no-underline" href="#">Tab</a>
    </li>
  </ul>

  <div class="hidden py-4 px-4 border-l border-b border-r" data-target="tabs.panel">
    Tab panel 1
  </div>

  <div class="hidden py-4 px-4 border-l border-b border-r" data-target="tabs.panel">
    Tab panel 2
  </div>

  <div class="hidden py-4 px-4 border-l border-b border-r" data-target="tabs.panel">
    <iframe width="560" height="315" src="https://www.youtube.com/embed/y3niFzo5VLI" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
  </div>
</div>

data-target="tabs.tab" defines which element is marked as a tab. The index of the tab is used to determine which panel to make visible.

data-target="tabs.panel" defines which panel is visible based upon the currently selected tab.

data-tabs-active-tab defines the list of classes that will be added/removed from the active tab when the active tab changes.

data-tabs-index="1" can be used to set the selected tab when the controller connects.

Popovers

import { Popover } from "tailwindcss-stimulus-components"
application.register('popover', Popover)

<p>
  Beginning in 2015, Google introduced what is called the
    <div class="popover inline-block" data-controller="popover" data-popover-translate-x="0" data-popover-translate-y="-128%" data-action="mouseover->popover#mouseOver mouseout->popover#mouseOut">
      <span class="underline">'local snack pack',</span>
      <div class="content hidden absolute max-w-xs bg-gray-300 rounded p-2" data-target="popover.content">
        Terrible name - we know. But the biggest name in SEO came up with it.
      </div>
    </div>
  which shows you local search results before normal organic results.
</p>

data-target="popover.content" defines which element will contain the actual content in the popover.

data-popover-translate-x="0" defines the css transform-translate X value used in positioning the popover.It can be anything from a percentage to rem units to pixels.

data-popover-translate-y="-128%" defines the css transform-translate Y value used in positioning the popover. It can be anything from a percentage to rem units to pixels.

Autosave (Rails-only)

Autosaving forms are really helpful for saving drafts of records. This Stimulus controller allows you to listen to fields to easily submit the form once the user has stopped typing.

Here's an example using Rails forms:

<%= form_with(model: post, data: { controller: "autosave", target: "autosave.form", action: "ajax:success->autosave#success ajax:error->autosave#error" }) do |form| %>
  <div class="form-group">
    <%= form.label :title %>
    <%= form.text_field :title, class: 'form-control', data: { action: "keyup->autosave#save" } %>
  </div>

  <div class="form-group">
    <%= form.label :body %>
    <%= form.text_area :body, class: 'form-control', data: { action: "keyup->autosave#save" } %>
  </div>

  <div class="form-group">
    <%= form.submit "Save and Publish", class: 'btn btn-primary' %>

    <span class="text-muted" data-target="autosave.status"></span>
  </div>
<% end %>

You can use data-target="autosave.form" to reference the form. This will be used with the Rails AJAX form submission.

The data-target="autosave.status" is used for displaying the status message of the autosave. This displays "Saving..." while the request is in progress and then "Saved!" if it was successful, "Unable to save!" if it failed.

Add data-action="keyup->autosave#save to listen to the keyup event and trigger an autosave. You can use other events like change for other field types like select.

Lastly, we have to handle the success and failure cases for the AJAX form submission.

data-action="ajax:success->autosave#success" is applied to the form to call the success method once the Rails ajax request succeeded.

data-action="ajax:error->autosave#error" is applied to the form to call the error method once the Rails ajax request failed.

Handling the form submission server-side

Your server side should check the params[:commit] text to see whether or not it should save as a draft or actually publish the record.

We recommend using a gem like Draftsman to help make the backend easier.

Toggle

<div data-controller='toggle' class="m-2">
  <div data-action='click->toggle#toggle touch->toggle#toggle' class="bg-gray-900 text-white p-6">
    What is the question?
  </div>
  <div data-target='toggle.toggleable' class="m-4 hidden">
    <p>This is the answer</p>
  </div>
</div>

In this example, clicking the question will toggle the hidden class. The hidden class is the default. If you wish to use a different class, you can use the data-toggle-class="custom-class" attribute.

<div data-controller='toggle' data-toggle-class='bg-red-900' class="m-2">
  <div data-action='click->toggle#toggle touch->toggle#toggle' class="bg-gray-900 text-white p-6">
    What is the question?
  </div>
  <div data-target='toggle.toggleable' class="m-4 bg-red-900">
    <p>This is the answer</p>
  </div>
</div>

Styling

All of the styles for the Stimulus components are configurable. Our examples above show some example styles you can use, but these components themselves don't require any specific styles.

Stimulus simply requires the data- attributes to be defined correctly to trigger actions and find targets.

Some components like the modal have some styles that are necessary for proper use in the browser. The container and backgrounds are separate so that you can have a fixed size container and the modal inside of it.

Extending Components

You can use inheritance to extend the functionality of any Stimulus components.

import { Dropdown } from "tailwindcss-stimulus-components"

class ButtonDropdown extends Dropdown {
  static targets = ["button"]

  connect() {
    super.connect();
    console.log("the value of button : ", this.buttonTarget.value)
  }
}

These controllers will automatically have access to targets defined in the parent class.

If you override the connect, disconnect or any other methods from the parent, you'll want to call super.method() to make sure the parent functionality is executed.
