Hello,

This is definitely possible! Consider using the following CSS Code as a guide:
[ch_pre type="css"]#side-panel {
right: -400px;
width: 400px;
}

.side-panel-left #side-panel {
left: -400px;
right: auto;
}

#side-panel .side-panel-wrap {
width: 430px;
}

#side-panel .widget {
margin-top: 40px;
padding-top: 40px;
width: 320px;
border-top: 1px solid #E5E5E5;
}

.side-push-panel.side-panel-open.stretched #wrapper,
.side-push-panel.side-panel-open.stretched .sticky-header .container {
right: 400px;
}

.side-push-panel.side-panel-open.stretched.device-xl .slider-inner,
.side-push-panel.side-panel-open.stretched.device-lg .slider-inner {
left: -400px;
}

.side-panel-left.side-push-panel.side-panel-open.stretched #wrapper,
.side-panel-left.side-push-panel.side-panel-open.stretched .sticky-header .container,
.side-panel-left.side-push-panel.side-panel-open.stretched .slider-inner {
