Answer 1

You should use show instead of show.value in your template. show.value is only available within the script tag in the composition api.

<div class="d-flex cursor-pointer justify-content-between border rounded bg-white mt-4 p-2 w-100 " @click="dropdown">
    <span>Purchase Requsition</span>
    <span class="material-icons fs-28 text-primary">
      {{show ? 'arrow_circle_down' : 'arrow_circle_down' }}
    </span>
</div>
