How to always show scroll bar on scheduler timeline wiew

[ikram]

hi, I want the scroll bar to always be visible. It appears when I start scrolling, but I want it to always be visible.
so   #scheduler .k-scheduler-content {
    overflow-y: scroll;
    } this isn't  working

please give some exaple on schedule timeline view

I try like this 

#scheduler .k-scheduler-content {
    overflow-x: scroll !important;
    overflow-y: auto;
    padding-bottom: 12px; /* scroll bar için extra alan */
}

#scheduler .k-scheduler-content::-webkit-scrollbar {
    -webkit-appearance: none;
}

#scheduler .k-scheduler-content::-webkit-scrollbar:horizontal {
    height: 12px;
}

#scheduler .k-scheduler-content::-webkit-scrollbar-thumb {
    background-color: rgba(0, 0, 0, .3);
    border-radius: 6px;
    border: 2px solid #ffffff;
}

#scheduler .k-scheduler-content::-webkit-scrollbar-track {
    background-color: #ffffff;
    border-radius: 6px;
}

but As in the picture, a slip occurred due to vertical scrolling.
