this is very simple and you can write one yourself.
gives you a component reference written by yourself

<!--
:tabItems tab[{name, isActive}...]nameisActivechang
:displayProp  
@change   tab:tabItem
ref.setActive(index)  change
ref.setPosition 
-->
<style rel="stylesheet/less" lang="less">
    @checked-color: -sharp4179FF;
    @text-color: -sharp3B435A;
    .slide-tab {
        width: auto;
        white-space: nowrap;
        background: -sharpFFFFFF;
        box-shadow: 0 1px 8px 0 rgba(0, 0, 0, 0.10);
        overflow-x: scroll;
        overflow-y: hidden;
        &::-webkit-scrollbar {
            display: none;
        }
        .slide-item {
            display: inline-block;
            position: relative;
            padding: 15px;

        .item-checked{
            color: @checked-color;
        }
        .slide-check {

            transition: all .2s;
        }
        .is-check {

    }

Why did I copy your code and reported an error? I added a js,less,cdn link myself
