为CKeditor 5工具栏创建自定义按钮

Question

I've managed to customize the header and highlight dropdowns for CKEditor 5 – classic editor build by creating a new custom build .
But I don't know how to add additional buttons to the toolbar. For example a fullscreen button. Current progress: github link

If you want to add existing buttons to the main toolbar, then you need to configure the config.toolbar . In your example it corresponds to these lines .

There's no fullscreen button at this moment. You can add +1 to the https://github.com/ckeditor/ckeditor5/issues/1235 to increase its priority or try to implement this feature on your own.

Basically, to create your own button you need to create a plugin which registers the button in the component factory and adds some actions that will be performed on the buttonView:execute event. You can follow the steps described in creating a simple plugin guide . A good and complementary reading about the UI library can be found here .
