Ckeditor5: How to add custom class when using writer.insertText

[crying2812]

Provide a description of the task

I using insertText() to create new paragraph, how can i add custom class for new element?

_What steps should be taken to fulfill the task?_
Here is my code:
`js
const docFrag = editor.model.change(writer => {

            const p1 = writer.createElement('paragraph', {class: 'flashback'});

            const docFrag = writer.createDocumentFragment();

            writer.append(p1, docFrag);

            writer.insertText('※   ※   ※', p1);

            return docFrag;
        });

`

Hi, thanks for the report. Did you allow class attribute on the paragraph element in the schema and provide proper conversion for this attribute? The simplified implementation could look like this:

import Plugin from '@ckeditor/ckeditor5-core/src/plugin';

export default class AllowClassAttribute extends Plugin {
    init() {
        const editor = this.editor;

        editor.model.schema.extend( 'paragraph', { allowAttributes: [ 'class' ] } );

        editor.conversion.attributeToAttribute( { model: 'class', view: 'class' } );
    }
}

Thanks @Mgsy, it worked.
