How can I add style (etc. padding-left: 10px;) or css class to an element over the custom Button and custom Context toolbar in TinyMCE 5?
This is what I've came so far:
editor.ui.registry.addButton('addstyle', {
icon: 'plus',
tooltip: 'Align image left',
onAction:
});
editor.ui.registry.addContextToolbar('imagealignment', {
predicate: function (node: any) {
return node.nodeName.toLowerCase() === 'img'
},
items: 'addstyle',
scope: 'node',
position: 'node'
});
I am missing what to write on onAction?
