Utilizing a single v-model for several elements

I am having an issue with a dropdown that is set to v-model="compose.Recipient".

Based on the value of "compose.Recipient", I need another dropdown to appear as shown below:

<div class="form-group" v-if="compose.Recipient==2" title="Select Class">
      <select v-model="compose.RecipientID" >
           <option v-for="value in a" v-bind:value="value">Class {{value}}</option>
      </select>
</div>
<div class="form-group" v-else-if="compose.Recipient==3" title="Select Grade">
      <select v-model="compose.RecipientID" >
           <option v-for="value in b" v-bind:value="value">Grade {{value}}</option>
      </select>
</div>
<div class="form-group" v-else-if="compose.Recipient==4" title="Select Bus">
      <select v-model="compose.RecipientID" >
           <option v-for="value in c" v-bind:value="value">Bus {{value}}</option>
      </select>
</div>

The issue is due to using v-if, it works when I use v-show instead.

Since I am using the same v-model="compose.RecipientID" for all dropdowns, I cannot switch to v-show from v-if.

Any suggestions on how to resolve this?

Thank you in advance.

Answer №1

To simplify the interface, consider consolidating three separate select elements into a single one by utilizing a computed property. This computed function can evaluate the value of compose.Recipient and dynamically return either a, b, or c. Utilize this computed property as the data source for the v-for directive within the single select element.

This approach streamlines the process by binding only one item to compose.RecipientID, eliminating the need to manage visibility toggles between multiple select elements.
