I am using vaadin grid web component in polymer and it gets data from a json. Its displaying data perfectly. But there isn’t much documentation about how to dynamically add or delete a row and items in it. I currently trying to delete rows based on multiple selection. But there is no way to that. I search online but I saw the java version of the vaadin grid have add and remove row methods but not in the vaadin grid web elements. Can anyone please refer me to a page where i can find a CRUD tutorial about it.
Or just share codes for adding, deleting and updating.
