Separating a button on menu

Hi there! Your question is theme-specific. You should contact your theme developer to ask if this is possible with the theme you are using. It looks like you’re using the theme, Avada. https://avada.theme-fusion.com/

The thing is my support from Avada expired already and I’m hoping someone can help me here. Do you think this won’t be fixed by CSS?

You can try some CSS to make adjustments.

li#menu-item-20019 {
    float: right;
}

and add a width to your .fusion-main-menu class.

.fusion-main-menu {
    width: calc(100% - 300px);
}

@mapk, I used your code and do some tweaking. It worked. Thank you so much!
