Common Patterns

With Tooltip

<template>
  <n-tooltip trigger="hover" placement="right">
    <template #trigger>
      <n-float-button position="relative">
        <n-icon><CashIcon /></n-icon>
      </n-float-button>
    </template>
    Add new item
  </n-tooltip>
</template>

Controlled Menu

<template>
  <n-float-button 
    position="relative" 
    type="primary" 
    menu-trigger="click"
    :show-menu="showMenu"
    @update:show-menu="showMenu = $event"
  >
    <n-icon><AddIcon /></n-icon>
    <template #menu>
      <n-float-button type="primary" @click="handleAction('edit')">
        <n-icon><EditIcon /></n-icon>
      </n-float-button>
      <n-float-button type="primary" @click="handleAction('delete')">
        <n-icon><DeleteIcon /></n-icon>
      </n-float-button>
    </template>
  </n-float-button>
</template>

<script setup>
import { ref } from 'vue'

const showMenu = ref(false)

const handleAction = (action) => {
  showMenu.value = false
  console.log('Action:', action)
}
</script>

Back to Top Alternative

<template>
  <n-float-button 
    v-show="showBackTop" 
    :right="40" 
    :bottom="80"
    @click="scrollToTop"
  >
    <n-icon><ArrowUpIcon /></n-icon>
  </n-float-button>
</template>

<script setup>
import { ref, onMounted, onUnmounted } from 'vue'

const showBackTop = ref(false)

const handleScroll = () => {
  showBackTop.value = window.scrollY > 200
}

const scrollToTop = () => {
  window.scrollTo({ top: 0, behavior: 'smooth' })
}

onMounted(() => window.addEventListener('scroll', handleScroll))
onUnmounted(() => window.removeEventListener('scroll', handleScroll))
</script>

Best Practices

1. Use primary type for main actions: Primary float button for the most important action

   <n-float-button type="primary">
     <n-icon><AddIcon /></n-icon>
   </n-float-button>
   

2. Position appropriately: Use right/bottom for typical FAB placement

   <n-float-button :right="24" :bottom="24">
     <n-icon><AddIcon /></n-icon>
   </n-float-button>
   

3. Group related actions: Use FloatButtonGroup for multiple related actions

   <n-float-button-group shape="circle">
     <!-- Multiple buttons -->
   </n-float-button-group>
   

4. Use menu for expandable actions: Collapsible menu for secondary actions

   <n-float-button menu-trigger="click">
     <template #menu>
       <!-- Secondary actions -->
     </template>
   </n-float-button>
   

5. Add tooltips for clarity: Provide context for icon-only buttons

   <n-tooltip>
     <template #trigger>
       <n-float-button>...</n-float-button>
     </template>
     Action description
   </n-tooltip>
   

6. Use relative position for inline: Set position="relative" when embedding in layout
