I would like all items to be closed when the page is opened

Dear superzu,
you can collapse all by enabling collapsible, and then using the method activate with a value of false, like this:
// construct the accordion
$('#<?php echo $uniquied;?>').sj_accordion({
collapsible: true,
...
});
Thanks

I tried to add in line 41 of the file defoult.php
collapsible: true,

this change has no effect. What am I wrong?

Thanks for support

Dear superzu

Please edit

collapsible: true,

to

collapsible: false,

thanks
