# Fab Floating Action Button
Floating action button component that displays a group of action buttons when pressed.
:::warning
Since `uni-app` components cannot monitor clicks outside themselves, to automatically close the `fab` when clicking elsewhere on the page, it is recommended to use the component library's `useQueue` hook (which will close all dropmenu, popover, toast, swipeAction, fab). Monitor click event bubbling on the root element of the page.
If there is a scenario where the user manually clicks somewhere other than `fab` to slide out the `fab`, you need to add `click.stop=""` to the clicked element (in this case, the button) to prevent event bubbling to the root element, avoiding triggering `closeOutside` which would close the manually opened `fab`.
:::
## Basic Usage
Set the trigger type through `type`, set the trigger position through `position`, set the opening direction of action buttons through `direction`, and set whether the floating button is disabled through `disabled`.
```html
```
```ts
import { useToast } from '@/uni_modules/wot-design-uni'
const { show: showToast } = useToast()
const type = ref<'primary' | 'success' | 'info' | 'warning' | 'error' | 'default'>('primary')
const position = ref<'left-top'
| 'right-top'
| 'left-bottom'
| 'right-bottom'
| 'left-center'
| 'right-center'
| 'top-center'
| 'bottom-center'>('left-bottom')
const direction = ref<'top' | 'right' | 'bottom' | 'left'>('top')
const disabled = ref(false)
```
```scss
:deep(.custom-button) {
min-width: auto !important;
box-sizing: border-box;
width: 32px !important;
height: 32px !important;
border-radius: 16px !important;
margin: 8rpx;
}
:deep(.custom-radio) {
height: 32px !important;
line-height: 32px !important;
}
```
## Action Menu Expand/Collapse
Control the expansion/collapse of the action button menu through `v-model:active`
```html
```
```ts
const active = ref(false)
```
## Draggable Button
```html
```
:::warning
After enabling dragging, the `direction` property will be invalid, and the pop-up direction will be automatically calculated based on the position after dragging. After dragging is completed, the button will automatically snap to the edge.
:::
## Custom Trigger
Customize the trigger through the `trigger` slot, `expandable` controls whether clicking the trigger expands/collapses the action button menu.

const handleClick = () => {
console.log('Clicked')
