Migration from v-tooltip 3 & 4 
Breaking changes 
Package rename 
Since the package has grown much past the v-tooltip directive, it has been renamed to floating-vue.
| v-tooltip | floating-vue | NPM Tag | Vue compatibility | 
|---|---|---|---|
| 4.x-beta.x | 2.x | latest | 3.x | 
| 3.x-beta.x | 1.x | vue2 | 2.x | 
Popperjs 
The positionning library has changed from popperjs 2 to floating-ui which is the spiritual successor.
Offset 
As it was too confusing, the offset is now two separate props: distance and skidding.
Before:
<VDropdown
  :offset="[0, 10]"
/>After:
<VDropdown
  distance="10"
  skidding="0"
/>Removed props 
- modifiers
- popperOptions
CSS 
The default padding for the dropdown theme has been removed. You can add your own padding like this:
.v-popper--theme-dropdown .v-popper__inner {
  padding: 6px;
}It will be added in a future Vue 3-only major version of floating-vue with CSS variables.
Modifiers 
floating-ui doesn't have a modifier system like popperjs. It has been replaced with new props.
Prevent overflow 
New props:
- preventOverflow(boolean)
- overflowPadding(px)
- shiftCrossAxis(boolean)
<!-- Before -->
<VDropdown :modifiers="[ { name: 'preventOverflow', enabled: false } ]" />
<!-- After -->
<VDropdown :prevent-overflow="false" /><!-- Before -->
<VDropdown :modifiers="[ { name: 'preventOverflow', options: { padding: 10 } } ]" />
<!-- After -->
<VDropdown :overflow-padding="10" /><!-- Before -->
<VDropdown :modifiers="[ { name: 'preventOverflow', options: { altAxis: true } } ]" />
<!-- After -->
<VDropdown shift-cross-axis />Flip 
New prop:
- flip(boolean)
<!-- Before -->
<VDropdown :modifiers="[ { name: 'flip', enabled: false } ]" />
<!-- After -->
<VDropdown :flip="false" />Arrow 
New prop:
- arrowPadding(px)
<!-- Before -->
<VDropdown :modifiers="[ { name: 'arrow', options: { padding: 12 } } ]" />
<!-- After -->
<VDropdown :arrow-padding="12" />New features 
v-popper__popper--arrow-overflow 
The v-popper__popper--arrow-overflow class is added on the v-popper_popper element when the arrow is overflowing past the reference bounds. By default, v-popper__arrow-container has display: none; which hides the arrow.
Auto max size 
You can now let floating vue resize the popper inner container to the available size (using max-width and max-height). It's very useful for a dropdown that should automatically shrink its size when it reaches the boundary.
