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.
This assumes that StimulusJS is already installed.
Add the tailwindcss-stimulus-components
module:
yarn add tailwindcss-stimulus-components
or
npm install tailwindcss-stimulus-components
First, you'll want to initialize StimulusJS and then you can import all the TailwindCSS components.
// Start StimulusJS
import { Application } from "@hotwired/stimulus"
const application = Application.start();
// Import and register all TailwindCSS Components
import { Alert, Autosave, Dropdown, Modal, Tabs, Popover, Toggle, Slideover } from "tailwindcss-stimulus-components"
application.register('alert', Alert)
application.register('autosave', Autosave)
application.register('dropdown', Dropdown)
application.register('modal', Modal)
application.register('tabs', Tabs)
application.register('popover', Popover)
application.register('toggle', Toggle)
application.register('slideover', Slideover)
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.
import { Alert } from "tailwindcss-stimulus-components"
application.register('alert', Alert)
To customize the appearance of alerts based on the kind of alert it is, you can do
something like this in: app/helpers/application_helper.rb
module ApplicationHelper
def tailwind_classes_for(flash_type)
{
notice: "bg-green-400 border-l-4 border-green-700 text-white",
error: "bg-red-400 border-l-4 border-red-700 text-black",
}.stringify_keys[flash_type.to_s] || flash_type.to_s
end
end
And then add something like this either directly in the layout file, or in a partial that's rendered directly by the layout:
<div class="fixed inset-x-0 top-0 flex items-end justify-right px-4 py-6 sm:p-6 justify-end z-30 pointer-events-none">
<div data-controller="alert" class="max-w-sm w-full shadow-lg rounded px-4 py-3 rounded relative bg-green-400 border-l-4 border-green-700 text-white pointer-events-auto">
<div class="p-2">
<div class="flex items-start">
<div class="ml-3 w-0 flex-1 pt-0.5">
<p class="text-sm leading-5 font-medium">

Alerts are set up to slide into view from the top-right side of the screen. Clicking on the "X" button will cause the alert to slide back out of view and be removed from the DOM.
data-alert-dismiss-after-value
can be provided to make the alert dimiss after x miliseconds. Default isundefined
.data-alert-show-delay-value
can be set to tell the alert to show itself after x miliseconds. Defaults to200
miliseconds.data-alert-remove-delay-value
can be set to tell the alert to hide itself after x milisconds. Defaults to1100
miliseconds.data-alert-show-class
is a set of all classes to apply on the alert when it's shown.data-alert-hide-class
is a set of all classes to apply on the alert when it's hidden.

Dropdowns are set up to toggle if you click on the dropdown button or any of the
options with in the dropdown menu (via data-action="click->dropdown#toggle
).
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 (data-action="click@window->dropdown#hide"
).
Users can also focus on the dropdown button if tabindex="0"
is included. They can toggle the dropdown with Space or Enter if the attribute data-dropdown-target="button"
is included on the button.
The data-dropdown-active-class
allows you add an active class to the dropdown menu. It will default to this.element
. You can also specify a target to use for the active class with the data-active-target
.
If you want a dropdown to be opened on page load you can set the data-dropdown-open-value="true"
as a data attribute.

the code above will toggle the dropdown component, if you needed to only perform a single action, such as show
or hide
. the dropdown component exposes such method.
data-action="click->dropdown#show"
data-action="click->dropdown#hide"
Animations for the dropdown menu (like the TailwindUI dropdowns) can be applied using these data attributes:
data-dropdown-invisible-class="opacity-0 scale-95"
data-dropdown-visible-class="opacity-100 scale-100"
data-dropdown-entering-class="ease-out duration-300"
data-dropdown-enter-timeout="300"
data-dropdown-leaving-class="ease-in duration-300"
data-dropdown-leave-timeout="300"
Here is an example:
<div class="relative"
data-controller="dropdown"
data-action="click->dropdown#toggle click@window->dropdown#hide"
data-dropdown-active-target="#dropdown-button"
data-dropdown-active-class="bg-teal-600"
data-dropdown-invisible-class="opacity-0 scale-95"
data-dropdown-visible-class="opacity-100 scale-100"
data-dropdown-entering-class="ease-out duration-100"
data-dropdown-enter-timeout="100"
data-dropdown-leaving-class="ease-in duration-75"
data-dropdown-leave-timeout="75">
<div data-action="click->dropdown#toggle click@window->dropdown#hide" role="button" data-dropdown-target="button" tabindex="0" class="inline-block select-none">

Slideovers are glorified dropdowns that include an additional overlay. Thus, the setup is equivalent to that of dropdowns, albeit you must specify an overlay
target. Animations are annotated similarly to dropdowns, just separate the classList
s of menu and overlay with a comma ,
:
data-slideover-invisible-class="-translate-x-full,opacity-0"
data-slideover-visible-class="translate-x-0,opacity-100"
data-slideover-entering-class=""
data-slideover-enter-timeout="300,300"

default action from running when clicking the element (e.g. a link from opening)
that opens the modal and set to false
to allow it. Default: true
.
data-modal-prevent-default-action-closing
may be set to true
to prevent the
default action from running when clicking the element (e.g. a link from opening)
that closes the modal and set to false
to allow it. Default: true
.
data-modal-restore-scroll-value
may be set to false
to disable
restoring scroll position.

data-tabs-target="tab"
defines which element is marked as a tab. The
index of the tab is used to determine which panel to make visible.
data-tabs-target="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-inactive-tab
defines the list of classes that will be
added/removed from the inactive tab when the active tab changes.
data-tabs-index="1"
can be used to set the selected tab when the
controller connects.
If you'd like to change the tab from a button or link outside of the tabs, you can call the same method and assign either data-id
or data-index
to select the tab.
<a data-action="click->tabs#change" data-index="1">Change tab by data-index</a>

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-popover-target="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-popover-target="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.
data-alert-dismiss-after-value
can be provided to make the popover dimiss after x miliseconds. Default is undefined
.
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-autosave-target="status"></span>
</div>
<% end %>
You can use data-autosave-target="form"
to reference the form. This
will be used with the Rails AJAX form submission.
The data-autosave-target="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.
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.
<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-toggle-target='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-toggle-target='toggleable' class="m-4 bg-red-900">
<p>This is the answer</p>
</div>
</div>
On some cases, you don't want to toggle something but rather do one action such as only show or hide the toggleable. the toggle controller exposes two such methods named hide
and show
this will only hide the toggleable.
<div data-action='click->toggle#hide touch->toggle#hide' class="bg-gray-900 text-white p-6">
What is the question?
</div>
while this only shows it
<div data-action='click->toggle#show touch->toggle#show' class="bg-gray-900 text-white p-6">
What is the question?

</div>
</span>
</div>
</div>
This will update the backgroundColor
by default but you can choose to have the color preview update the color
instead by setting the data-color-preview-style="color"
attribute of the color preview controller.
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.
You can use inheritance to extend the functionality of any Stimulus components.
import { Dropdown } from "tailwindcss-stimulus-components"
export default 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.
To develop locally, run npx serve
and open your browser to the URL it serves on.
