Description

Problem to solve

v-textarea has a template slot for label which is useful to customize the label.

My current use case is to have a smooth transition if the label changes based on previous user input:

<v-textarea v-model="inputMessage">
  <template #label>
    <v-fade-transition mode="out-in">
      <div :key="inputMessageLabel">{{ inputMessageLabel }}</div>
    </v-fade-transition>
  </template>
</v-textarea>

inputMessageLabel changes based on previous user input.

This is cool, but that type of changing message would better be placed as a placeholder. Unfortunately I can't use a transition in the placeholder like I'm doing here, because there's no slot for it.

Proposed solution

Have a slot for placeholder that works analog to the slot for label

Research direction
The VTextarea component likely has a template with a label slot. To implement, find the VTextarea component file (e.g., packages/vuetify/src/components/VTextarea/VTextarea.ts or .vue) and add a placeholder slot in the template following the pattern of the existing label slot. Ensure the placeholder slot is properly typed and documented. Check if there are any existing tests for slots that can be extended.
