Adding Scrolling to Autocomplete Results in Administration

Hi everyone,

I would like to have the option to scroll through the autocomplete results that appear in a dropdown when searching for something.

Looking trough the forum I found the following code, but don't know where to put it to make it work since the original post didn't mention it.

.dropdown-menu {
max-height: 250px;
max-width: 450px;
overflow-x: hidden; /* avoid horizontal scrolling */
}

.ui-autocomplete{
max-height: 200px;
overflow-y: auto;
overflow-x: hidden;
}

Could anybody help me out?

I'm using OpenCart 3.0.3.9

This would require some modifications. By default it uses jquery autocomplete calls, with a limited number of results, to be narrowed down by typing in more characters to the search term.

I was able to install a modification to increase the number of results shown, but now I need to scroll down to see all of them. Do you know where I can do that?
