Is there anyway we can add a custom toolbar in Angular code?
https://www.tinymce.com/docs/demo/custom-toolbar-menu-button/ This is the link to custom toolbar.
I need to get this in Angular5.
You can pass your own configuration to the editor via our component for integrating TinyMCE into Angular:

In particular please see the init parameter.
