[stratdev3]

With absolute and bottom props, the VProgressLinear should be align to the bottom border inside a v-toolbar.

Example :

• correct in v2.x : https://codepen.io/cp10/pen/OJZdBzg?editors=101
• incorrect in v3.0b14 : https://codepen.io/cp10/pen/jOxdeYx?editors=101

Other components use the location and position composables for this

@KaelWD so what's the plan to fix the issue ?

@KaelWD so what's the plan to fix the issue ?

He probably means something like this:

// located in VAppBar.tsx

location: {
  type: String as PropType<'top' | 'bottom'>,
  default: 'top',
  validator: (value: any) => ['top', 'bottom'].includes(value),
}

Thank you for the fix. The documentation is outdated, since the bottom prop is no longer supported (progress bar is shown on top, not bottom): https://next.vuetifyjs.com/en/components/progress-linear/#toolbar-loader

Also, eslint-plugin-vuetify complains about the absolute prop, even though it seems supported on this component:

<v-progress-linear absolute color="secondary" />
ESLint: 'absolute' has been removed(vuetify/no-deprecated-props)
