off-canvas position left doesn't works properly

Ok I to hear you soon. Thanks

It loads the offcanvas-toggler html code inside #sp-logo column instead #sp-menu column.

Hi. Yes, this is exactly what happens (not a bug, but not quite a good solution from Joomshaper). To solve the problem, you need to keep offcanvas on the right and configure it to the left via CSS and Menu col settings for mobile.

What's the specific CSS code have I to write, please? If I keep offcanvas on the right I can put it on the left column but when I click on it it's show the menu transition on the right and from right-to-left, I need to show it on the left and transition from left-to-right. Thanks

Or wait for support answer

Ok, I published the website, you can now refresh and see it here. Thanks

Now it is in left.

Set it in right

Ok, now I set it to right.

As far as I see order -1 for Menu col you have already set up.

Here is the remaining code

body.ltr #offcanvas-toggler.offcanvas-toggler-right {
    float: left;
    margin-left: 0;
    margin-right: 20px;
}
body.ltr.offcanvs-position-right .body-wrapper,
body.ltr.offcanvs-position-right .offcanvas-menu {
    right: auto !important;
    left: -300px;
}
body.ltr.offcanvs-position-right.offcanvas-active .body-wrapper,
body.ltr.offcanvs-position-right.offcanvas-active .offcanvas-menu {
    left: 0;
}
