Vue analog keyboard

this demo is used, but the keyboard is not rendered. Can you take a look at the list rendering block on this demo source code, or is there a recommended keyboard plug-in (which needs to be used in the self-service terminal)

is written according to the code in demo, but the li under ul is not rendered. I hope kindhearted people can help solve
