Hello there!

Thanks for your query.

Please use the following code in your custom.css file:

.offcanvas-menu .offcanvas-inner ul.menu>li.menu-parent li.menu-parent .menu-toggler{
    transform: translateY(-95%)!important;
    -webkit-transform: translateY(-95%)!important;
}

Moreover, I have checked your link and there is a extra closing brace appear, so please remove the last unnecessary closing brace from the end of the file https://prnt.sc/1zb78k6 and then put the above code there. Otherwise the code may not be effective.

Best Regards
