How to decrease list height in v-select vuetify3

Question

I can't decrease list height... list height becomes full screen height

I tried a lot of ways, but nothing happened

That is weird, as per default, the (max-)height is set to 310px (see source).

But you can change the height by passing a configuration object to the underlying v-menu through the :menu-props prop. You have to adjust the :max-height:

<v-select
  :menu-props="{
    'max-height': 310
   }"
/>

const { createApp, ref, computed} = Vue;
const { createVuetify } = Vuetify
const vuetify = createVuetify()
const app = {
  setup(){
    const items = Array.from({length: 100}, (_,i) => `Options ${i+1}`)
    const maxHeightNumber = ref(0)
    const maxHeight = computed(() => maxHeightNumber.value  > 0 ? maxHeightNumber.value + 'px' : 'auto')
    
    return { items, maxHeight, maxHeightNumber}
  }

}
createApp(app).use(vuetify).mount('#app')
