Any suggestion how it can be added as TemplateRenderer to grid column like <clipboard-helper> without java server side class? Tried but don’t know how to wrap span with content to copy.
There’s no custom element like that. You will be better off just by implementing it in the template code, look at the sources.
Tried, but on safari text is copied only first time, on firefox doesn’t work at all. Can you provide some short example of what you suggested please?
