Stimulus Read More
A Stimulus controller to show more or less text.
Installation
$ yarn add stimulus-read-more
And use it in your JS file:
// Probably in app/javascript/controllers/index.js
import { Application } from '@hotwired/stimulus'
import ReadMore from 'stimulus-read-more'
const application = Application.start()
application.register('read-more', ReadMore)
👀 Demo
See demo →Usage
This controller is based on the Line-clamp CSS property.
It will update the CSS variable --read-more-line-clamp
on the element with the value 'unset'
to show all the content.
In your CSS:
.my-content {
overflow: hidden;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: var(--read-more-line-clamp, 2);
}
In this case, --read-more-line-clamp
is undefined
and 2
is the number of lines displayed by default.
In your view:
<div data-controller="read-more" data-read-more-more-text-value="Read more" data-read-more-less-text-value="Read less">
<p class="my-content" data-read-more-target="content">
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna
aliqua. Ut enim ad minim veniam.
</p>
<button data-action="read-more#toggle">Read more</button>
</div>
🛠 Configuration
Attribute | Default | Description | Optional |
---|---|---|---|
data-read-more-more-text-value | undefined | Text to display to show more text. | ✅ |
data-read-more-less-text-value | undefined | Text to display to show less text. | ✅ |
🎛 Extending Controller
You can use inheritance to extend the functionality of any Stimulus component:
import ReadMore from 'stimulus-read-more'
export default class extends ReadMore {
connect() {
super.connect()
console.log('Do what you want here.')
}
// Function to override on toggle.
toggle(event) {}
// Function to override when the text is shown.
show(event) {}
// Function to override when the text is hidden.
hide(event) {}
}
This controller 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.
