Hide close or remove button ( 'X' ) for first dragged node.

[Co-Maheshh]

Kindly help me to add restriction so that user cannot delete first dragged node.
Have a look in the code tried this but its not working.

mythis.editor.on("nodeRemoved", (id) => {
if(id == 0){
this.toast.error("Cannot remove")
return false;
}
})

you can set a display: none; in the drawflow-delete class.

in my case I used the nodeMoved event to change the value of my css variable

JS

this.editor.on("nodeMoved", function() {
  document.documentElement.style.setProperty('--dfDeleteDisplay', 'none');
});

CSS

:root {
  --dfDeleteDisplay: 'block';
}

.drawflow-delete {
  display: --dfDeleteDisplay;
}
