How does the dynamic addition tab of layui show a horizontal scroll bar instead of just a drop-down?

dynamic switching tab in the backend template provided by the official website is

layuitab

with left and right click scrolling.

after looking at the document for a long time, I can"t find the official website template. How to implement the tab with left and right clicks on the official website? is there any document configuration item? I still have to write it myself.
