Hi insity,
I understand what you need. Unfortunately there is no setting about it, but can be achieved fairly easy with some lines of css and js. In order to do this just follow the instructions below in case you are using
nopCommerce version 3.50:
1. Open the Plugins\SevenSpikes.Nop.Plugins.RealOnePageCheckout\Themes\Motion\Content\RealOnePageCheckout.css file and add the following on line 77 :
.ropc .order-summary-content .section-body {
display: block;
}
This will make the order summary expanded by default.
2. Open the Plugins\SevenSpikes.Nop.Plugins.RealOnePageCheckout\Views\RealOnePageCheckout\RealOnePageCheckout.cshtml file and edit it as shown below:
<script type="text/javascript">
$(document).ready(function () {
if ($.getSpikesViewPort().width <= 768) {
$('.panel-group.panel-group-right-middle').detach().insertBefore('.panel-group.panel-group-left');
}
$('.page-body').on('click', '.ropc .section-title', function () {
var e = window, a = 'inner';
if (!('innerWidth' in window)) {
a = 'client';
e = document.documentElement || document.body;
}
var result = { width: e[a + 'Width'], height: e[a + 'Height'] };
if (result.width < 769) {
$(this).siblings('.section-body').slideToggle('slow');
}
});
});
</script>
The line in bold is the one that should be added.
Hope that helps.
