Well the plugins itself says it open on click. I sometime use this trick, and that also help you too.
You have to trigger click on page laod. Suppose your button/link selector is class named “clickmetoopen” I write it like
$(document).ready(function(){
$(".clickmetoopen").trigger("click");
});
Or if your selector is id something like “clickmetoopen” the above code should be work for you like
$(document).ready(function(){
$("#clickmetoopen").trigger("click");
});
