Button Tooltip

btn.getElement().setProperty(“title”, “”+“Help”+“
”+“Center”); not work any idea

HTML is not allowed in the title attribute https://html.spec.whatwg.org/multipage/dom.html#the-title-attribute

also, you probably want .setAttribute instead of .setProperty

can you please give me a sample code

btn.getElement().setAttribute("title", "No html supported here");
