i have a component in vue.js 3 
i want that scroll down automatically infinite
how can i do that?
To make a component in Vue.js 3 scroll down automatically infinitely, you can use the `setInterval()` function to continuously scroll the element. Here's an example:

    <template>
      <div class=scrollable ref=scrollable>
        <!-- Your content here -->
      </div>
    </template>

    <script>
    export default {
      mounted() {
        const scrollable = this.$refs.scrollable;
        setInterval(() => {
          scrollable.scrollTop += 1; // Change the scroll speed as needed
        }, 50); // Change the scroll interval as needed
      }
    }
    </script>
    
    <style>
    .scrollable {
      height: 200px; /* Change the height as needed */
      overflow: auto;
    }
    </style>

In this example, we have a `div` with the class `scrollable` that contains your content. We add a `ref` attribute to this element so we can access it in our component. In the `mounted` lifecycle hook, we use `setInterval()` to continuously scroll the element by increasing the `scrollTop` property by 1 every 50 milliseconds. You can adjust the scroll speed and interval to fit your needs. Finally, we add some CSS to make the element scrollable with a fixed height.
