A color picker 100% functional !
See original GitHub issueEDIT: if you are using Trix 2.0+ read the tutorial but instead of using this stimulus_controller, please use the stimulus_controller here: https://github.com/basecamp/trix/issues/985#issuecomment-1307422240
After a good time of reading issues and thinking I finally could create a fully functional color picker for Trix
This also works when reloading the editor page because I call reset after the config.
I also added text-align center icon to center blocks
For this to work, just wrap your rich_text_area in a div with data-controller="trix" and add a data: { trix_target: 'editor' } to the rich_text_area
<div class="control" data-controller="trix">
<%= f.rich_text_area :description, placeholder: t('products.edit.description_placeholder'),
data: { trix_target: 'editor' } %>
</div>
Also add a stimulus controller called trix-controller.js and then update the stimulus manifest
update the Stimulus manifest with ./bin/rails stimulus:manifest:update
import { Controller } from '@hotwired/stimulus'
import Trix from 'trix'
// Connects to data-controller="trix"
export default class extends Controller {
static targets = ['editor', 'foregroundColorPicker', 'backgroundColorPicker']
connect () {
this.initTrix()
this.reloadOriginalContent()
}
initTrix () {
if (this.hasForegroundColorPickerTarget) { return }
Trix.config.blockAttributes.heading1.tagName = 'h3'
this.addForegroundButtonInToolbar()
this.addBackgroundButtonInToolbar()
this.addTextAlignCenterButtonInToolbar()
}
reloadOriginalContent () {
this.editorTarget.reset()
}
openForegroundColorPicker () {
this.foregroundColorPickerTarget.click()
}
openBackgroundColorPicker () {
this.backgroundColorPickerTarget.click()
}
foregroundColorChanged () {
this.editorTarget.editor.activateAttribute('foregroundColor', this.foregroundColorPickerTarget.value)
}
backgroundColorChanged () {
this.editorTarget.editor.activateAttribute('backgroundColor', this.backgroundColorPickerTarget.value)
}
addForegroundButtonInToolbar () {
Trix.config.textAttributes.foregroundColor = {
styleProperty: 'color',
inheritable: true
}
this.element
.querySelector('.trix-button-group.trix-button-group--text-tools')
.insertAdjacentHTML('beforeend', this.foregroundColorButtons)
}
addBackgroundButtonInToolbar () {
Trix.config.textAttributes.backgroundColor = {
styleProperty: 'backgroundColor',
inheritable: true
}
this.element
.querySelector('.trix-button-group.trix-button-group--text-tools')
.insertAdjacentHTML('beforeend', this.backgroundColorButtons)
}
addTextAlignCenterButtonInToolbar () {
Trix.config.blockAttributes.textAlignCenter = {
tagName: 'centered-div'
}
this.element
.querySelector('.trix-button-group.trix-button-group--block-tools')
.insertAdjacentHTML('beforeend', this.textAlignButtons)
}
get foregroundColorButtons () {
return `<input type="color" style="width:0;height:0;padding:0;margin-top:20px;visibility:hidden"
data-trix-target="foregroundColorPicker" data-action="trix#foregroundColorChanged">
<button type="button" class="trix-button" data-action="click->trix#openForegroundColorPicker" title="Text color">
<span class="icon"><i class="fas fa-palette fa-lg"></i></span>
</button>`
}
get backgroundColorButtons () {
return `<input type="color" style="width:0;height:0;padding:0;margin-top:20px;visibility:hidden"
data-trix-target="backgroundColorPicker" data-action="trix#backgroundColorChanged">
<button type="button" class="trix-button" data-action="click->trix#openBackgroundColorPicker" title="Text background color">
<span class="icon"><i class="fas fa-fill-drip fa-lg"></i></span>
</button>`
}
get textAlignButtons () {
return `<button type="button" class="trix-button" data-trix-attribute="textAlignCenter">
<span class="icon"><i class="fas fa-align-center fa-lg"></i></span>
</button>`
}
}
You may want to replace the icon <span class="icon"><i class="fas fa-palette"></i></span> (I use fontawesome, feel free to use whatever you like, maybe a 🎨 icon would work)
this solves https://github.com/basecamp/trix/issues/498 https://github.com/basecamp/trix/issues/606 https://github.com/basecamp/trix/issues/655 and many others.
For the centered text you will need to:
Add this css
centered-div {
display: block;
text-align: center;
}
Also add centered-div as allowed tags (I have this in my application.rb)
config.after_initialize do
ActionText::ContentHelper.allowed_attributes.add 'style'
ActionText::ContentHelper.allowed_attributes.add 'controls'
ActionText::ContentHelper.allowed_attributes.add 'poster'
ActionText::ContentHelper.allowed_tags.add 'video'
ActionText::ContentHelper.allowed_tags.add 'source'
ActionText::ContentHelper.allowed_tags.add 'centered-div'
end

UPDATE: for trix 2.0+ the controller is slightly different (and better, less hacky)
Thanks, you are right. With the upgrade to 2.0.1 we do not need the call anymore. 👍
