Main Menu undercolor settings

it works great on line https://www.turceksro.sk/index.php and I would need it to work on https://www.turceksro.sk/xtuweb2/ as well
I can't insert a photograph here

Not the color of the cursor, but the background color of the menu on which the cursor is. When I move the cursor to another menu item, the background of the menu where the cursor is no longer changes to white, and the background of the menu that the cursor comes to changes to, for example, gray

Thank you, but I thought it should be like on my old page at this link https://www.turceksro.sk/index.php

Hi. Perhaps you use the wrong terminology, but your old page does not have the background color changes on hover, there is only the text color changes on hover

The change in background color would look like this.

Therefore, you should provide an accurate explanation of what you want.

OK, I'll try to explain it differently.
I would need to somehow set the background color under the first, second and third level menu text on mouseover. So that not only the text but also the background under the text is colored. I am attaching pictures
this is how it is now

Hi.

Now it’s clear

.sp-megamenu-parent .sp-dropdown li.sp-menu-item > a {
    display: block;
    padding-inline: 20px;
    margin-inline: -20px;
}
.sp-megamenu-parent .sp-dropdown li.sp-menu-item > a:hover {
    color: #e03731;
    background-color: #eee;
}
