increase with of the "Slideout-Navigation"

Hi there,

try adding this CSS:

#generate-slideout-menu.offside {
    --oc-width: 300px;
    width: var(--oc-width);
}

#generate-slideout-menu.offside--right.is-open {
    transform: translate3d( calc( -1 * var(--oc-width) ) ,0,0);
}

#generate-slideout-menu.offside--right {
    left: auto;
    right: calc( -1 * var(--oc-width) );
}

I have set it to 300px, you can change the value in this line: --oc-width: 300px;
