Dropdown menu not working properly

[W96K03]

Hey everyone! I am working on my website. The dropdown menu doesn't work the way I want.

See photo for example.

I want it to be like this:

This is the timber.scss.liquid code:

/*================ Module | Site Nav and Dropdowns ================*/
.site-nav {
cursor: default;
margin: 0;
margin-left: -$gutter / 2;
}

.site-nav__item {
position: relative;
display: inline-block;
margin: 100;

li {
display: inline;
}
}

.site-nav--mobile {
@extend .site-nav;
margin-left: -10px;

&.text-right {
margin: 0 -10px 0 0;
}
}

.site-nav__link {
display: inline;
text-decoration: none;
padding: $gutter / 2;
white-space: nowrap;
font-size: em(14px);

.icon-arrow-down {
position: relative;
top: -2px;
padding-left: $gutter / 4;
font-size: 10px;
}
}

.site-nav__dropdown-link {
.icon-arrow-down {
position: absolute;
top: 50%;
right: $gutter / 2;
font-size: 10px;
@include transform("translateY(-50%) rotate(-90deg)");
}
.site-nav__dropdown-grandchild & {
white-space: normal;
}
}

.site-nav__link--icon {
padding-left: $gutter / 4;
padding-right: $gutter / 4;
}

.site-nav--mobile {
.site-nav__link {
display: inline-block;
}

.icon {
font-size: em(30px);
}
}

/*================ Dropdowns ================*/
.site-nav__dropdown {
opacity: 0;
display: inline-block;
position: absolute;
left: 0;
margin: 0;
z-index: $zindexNavDropdowns;
pointer-events: none;

a {
background-color: $colorNav;
text-align: left;

&:hover,
&:active {
background-color: darken ($colorNav, 10%);
}
}

&.nav-outside {
left: auto;
right: 0;
}
}

.site-nav__dropdown-grandchild {
position: absolute;
top: -10px; // Match dropdown padding
left: 100%;
width: 100%;
margin: 0;
z-index: $zindexNavDropdowns;
opacity: 0;
pointer-events: none;

a {
background-color: $colorNav;

&:hover,
&:active {
background-color: ($colorNav, 10%);
}
}

ul {
background-color: $colorNav;
padding: ($gutter / 3) 0;
// Grand children dropdown is 2px off parent dropdown
margin: 0 0 0 2px;
}

&.nav-outside {
left: -100%;
}
}

And this is the theme.scss.liquid code
