QMenu with vue3 && ts && Composition API

[ghost]

I want to make a search bar with prompt in menu

<q-input ref="input" rounded autofocus standout bottom-slots clearable debounce="300" :loading="loadingState" v-model="text"
           :dense="dense" :label="label"
           @update:model-value="inputChange"
  >
    <template v-slot:prepend>
      <q-avatar>
        <q-btn icon='mic'/>
      </q-avatar>
    </template>
    <template v-slot:append>
      <q-avatar>
        <q-btn icon='search'/>
      </q-avatar>
    </template>
    <q-menu fit :target="false" ref="menu" transition-show="jump-down"
            transition-hide="jump-up">
      <!-- max for seven -->
      <q-list
        style="min-width: 100px"
      >
        <q-item clickable>
          <q-item-section>New tab</q-item-section>
        </q-item>
        <q-item clickable>
          <q-item-section>New incognito tab</q-item-section>
        </q-item>
        <q-separator/>
        <q-item clickable>
          <q-item-section>Recent tabs</q-item-section>
        </q-item>
        <q-item clickable>
          <q-item-section>History</q-item-section>
        </q-item>
        <q-item clickable>
          <q-item-section>Downloads</q-item-section>
        </q-item>
        <q-separator/>
        <q-item clickable>
          <q-item-section>Settings</q-item-section>
        </q-item>
        <q-separator/>
        <q-item clickable>
          <q-item-section>Help &amp; Feedback</q-item-section>
        </q-item>
      </q-list>
    </q-menu>
  </q-input>

I set menu target is false because I want control menu display

and there is code in Composition API, I did test for menu show/toggle and nothing happened

const menu = ref<QMenu>()
    // after the component has mounted into DOM:
    onMounted(()=>{
      console.log(menu.value?.show)
      menu.value?.toggle()
    })
    function showMenu() {
      menu.value?.toggle()
    }

I print the menu Value, and the show method exists, but it not work
Maybe it is target="false" problem?? I am not sure

My bad, I find select component instead of this
