The editor is showing the toolbar buttons based on the screen size. They can be customized using the following options:
- toolbarButtons for large devices (≥ 1200px)
- toolbarButtonsMD for medium devices (≥ 992px)
- toolbarButtonsSM for small devices (≥ 768px)
- toolbarButtonsXS for extra small devices (< 768px)
If you have set the options above and you're still not seeing all the buttons, please make sure you're including the editor plugins which are enabling those buttons.
