Above is wat my page looks like. For some reason when i try my fiddle, it does what I'm expecting. But in my code this doesn't work.
回答1:
remove active:false it will open first option by default.
see DEMO
$("#accordion").accordion({
collapsible:true,
});
second option with active:false. trigger click event at the end of code.
$('h3:eq(0)').trigger('click');
see DEMO
