How to add font types on Quill js with toolbar options?

Question

I have made a rich text area made with Quill js. I have the next options for the tool bar:

new Quill('#quilljs-container', {
    modules: {
        toolbar: [
           ['bold', 'italic', 'underline', 'strike'],        // toggled buttons
           ['blockquote', 'code-block', 'link'],

           [{ 'header': 1 }, { 'header': 2 }],               // custom button values
           [{ 'list': 'ordered'}, { 'list': 'bullet' }],
           [{ 'script': 'sub'}, { 'script': 'super' }],      // superscript/subscript
           [{ 'indent': '-1'}, { 'indent': '+1' }],          // outdent/indent
           [{ 'direction': 'rtl' }],                         // text direction

           [{ 'color': [] }, { 'background': [] }],          // dropdown with defaults from theme
           [{ 'font': [] }],
           [{ 'align': [] }],

           ['clean']                                         // remove formatting button
       ]
    },
    theme: 'snow'
});

<!-- quill js container -->
<div id="quilljs-container">  </div>

<!-- Add quill js on the project -->
<script src="https://cdn.quilljs.com/1.0.0/quill.js"></script>

Currently, when I try to add more types editing the 'font' option on toolbar (e.g. 'font': ['arial']), the select options just display "Sans Serif" instead of display the "Arial" option. What I spect is see the default options ("Sans Serif", "Serif", "Monospace") plus custom options that I want to add.

Also, I have tried the customizing attributors shown on the documentation, but with my current configuration, it just display just the default options. Maybe I'm missing something.

I hope I was clear with my doubt and someone could help me.

UPDATE:

Just to be a little more clear, I am trying to add more fonts following the Quill Container configuration

Container: At the simplest level, toolbar controls can be specified by a simple array of format names.

Answer 1

This is what you need.

The process is like this you need 4 components:

1. A select tag with a ql-font class. This will contain the new font options.
2. Add the new fonts to the whitelist. This has to be defined before you call the the Quill constructor in Javascript.
3. Define the font-family for each label in the dropdown. Example: font-family: "Inconsolata"
4. Define the content font-families that will be used in the text area. Following the example in the 3rd component: .ql-font-inconsolata { font-family: "Inconsolata";}

Update:

I read the documentation in order to help you and they mention that

At the simplest level, toolbar controls can be specified by a simple array of format names...

Alternatively, you can manually create a toolbar in HTML by passing the DOM element or selector into Quill; and that is the solution presented in this answer. On the other hand, the documentation does not mention but after trying many ways to load data using an array (without any success), I noticed that is not possible. So, here is my contribution and the reason why I posted this update. I made the equivalences (JS and HTML) for the manual implementation.

A custom toolbar can be created using HTML and a JS constructor. The constructor will receive the #toolbar-container as a toolbar in the modules section.

Then, you can generate the same structure using only HTML tags. The concept is very similar. For example:

• If in JS we declare an array like this: ['bold', 'italic', 'underline', 'strike'] in HTML will be:

<span class="ql-formats">
    <button class="ql-bold"></button>
    <button class="ql-italic"></button>
    <button class="ql-underline"></button>
    <button class="ql-strike"></button>
</span>

• In JS is [{ 'header': 1 }, { 'header': 2 }] in HTML will be

<span class="ql-formats">
   <button class="ql-header" value="1"></button>
   <button class="ql-header" value="2"></button>
</span>

So, here you have a complete example in this code snippet:

// Add fonts to whitelist
let Font = Quill.import('formats/font');
// We do not add Sans Serif since it is the default
Font.whitelist = ['inconsolata', 'roboto', 'mirza', 'arial'];
Quill.register(Font, true);


// We can now initialize Quill with something like this:
let quillObj = new Quill('#quilljs-container', {
  modules: {
    toolbar: '#toolbar-container'
  },
  placeholder: 'This is a font test...',
  theme: 'snow'
});

Answer 2

You CAN use the JavaScript constructor to create a custom font selection.

From the Quill Quickstart page here's the basic HTML -

<!-- Include stylesheet -->
<link href="https://cdn.quilljs.com/1.3.6/quill.snow.css" rel="stylesheet">

<!-- Create the editor container -->
<div id="editor">
  <p>Hello World!</p>
  <p>Some initial <strong>bold</strong> text</p>
  <p><br></p>
</div>

<!-- Include the Quill library -->
<script src="https://cdn.quilljs.com/1.3.6/quill.js"></script>

The code required in the JavaScript initialiser is along the lines of the following:

let Font = Quill.import('formats/font');
Font.whitelist = ['times-new-roman', 'arial'];
Quill.register(Font, true);

let toolbarOptions = [
    [{ 'font': ['', 'times-new-roman', 'arial'] }],

    ['clean']                                         // remove formatting button
];

let quill = new Quill('#editor', {
    modules: {
        toolbar: toolbarOptions
      },
    theme: 'snow'
    });

You also need to add the following to your stylesheet where the names in the CSS selectors are those names in the above JavaScript:

/* Set droplist names - -item is the currently selected font, -label is the font's appearance in the droplist*/
.ql-snow .ql-picker.ql-font .ql-picker-label[data-value='']::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value='']::before
{
  content: 'Default';
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value='times-new-roman']::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value='times-new-roman']::before
{
  content: 'Times New Roman';
  font-family: 'Times New Roman';
}

.ql-snow .ql-picker.ql-font .ql-picker-label[data-value='arial']::before,
.ql-snow .ql-picker.ql-font .ql-picker-item[data-value='arial']::before
{
  content: 'Arial';
  font-family: 'Arial';
}

/****************************************************
Set the font-family content used for the HTML content.
*****************************************************/
.ql-font-arial {
  font-family: 'Arial';
}

.ql-font-times-new-roman {
  font-family: 'Times New Roman';
}
