TinyMCE from a CDN (what they call 'Cloud') is not free any more but if you have a plan, you can add something like this to your custom.js file:
Code:
$(document).on('ready pjax:scriptcomplete',function(){
$.getScript('https://cloud.tinymce.com/stable/tinymce.min.js', function(data, textStatus, jqxhr) {
tinymce.init({
selector: '.text-item textarea',
menubar: false,
setup: function (editor) {
editor.on('change', function () {
tinymce.triggerSave();
});
},
plugins: [
'advlist autolink lists link image charmap print preview anchor textcolor',
'searchreplace visualblocks code fullscreen',
'insertdatetime media table contextmenu paste code help wordcount'
],
toolbar: 'insert | undo redo | formatselect | bold italic backcolor forecolor | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | code paste removeformat | help',
content_css: [
'//fonts.googleapis.com/css?family=Lato:300,300i,400,400i',
'//www.tinymce.com/css/codepen.min.css'
]
});
});
});
