I've added an insertdatetime button to my toolbar, which has an icon + a drop-down menu.
I've removed all the menu options, because I only want a single-click button, that inserts current date/time.
Is it possible to remove the drop-down (menu) part of the button?
This isn't possible out of the box, as the default button in the Insert Date/Time plugin will always use a split toolbar button. If you want just a regular toolbar button you'd need to create a custom button. Here's an example to show how this can be done by making use of the mceInsertDate
command provided by the Insert Date/Time plugin: https://fiddle.tiny.cloud/9Phaab
editor.ui.registry.addButton('insertdate', {
icon: 'insert-time',
tooltip: 'Insert date',
onAction: () => editor.execCommand('mceInsertDate')
});
