+})
+</script>
+```
+
+It can also accept a `ref` as the first argument.
+
+```vue
+<script setup lang="ts">
+import { useParentElement } from '@vueuse/core'
+import { useTemplateRef } from 'vue'
+
+const tooltip = useTemplateRef('tooltip')

+
+onMounted(() => {
+  console.log(tooltipWrapper.value)
+})
