Buttons

Type: Object

Default: object

The buttons.tags setting indicates which buttons in the toolbar should be highlighted when the cursor is in a specific tag.

By default, the object contains these values:

{
    'b': ['bold'],
    'strong': ['bold'],
    'i': ['italic'],
    'em': ['italic'],
    'del': ['deleted'],
    'a': ['link']
}

You can add your value:

ArticleEditor('#entry', {
    css: '/your-article-dist-path/',
    buttons: {
        tags: {
            'u': ['underline']
        }
    }
});
