Categories checkboxes as dropdown

Some sites have many categories and listing them all in a horizontal scroll panel might not be optimal. Could you consider using multi-select dropdown?

Example: https://demos.codexworld.com/multi-select-dropdown-list-with-checkbox-jquery/

The example script above will “dropup” by adding this css:

.ms-options-wrap > .ms-options {
    bottom: 10px;
    max-height: 400px !important;
}

Another advantage with this solution is the search functionality.
