Vue 3: Issues with Conditional Rendering of Form Fields Based on User Role Selection

I'm performance testing and I'm relatively new to this, so bear with me... I'm working on a Vue 3 application where I need to display different form fields based on the user role that a user selects from a dropdown. The issue arises when I change the role; the previously filled data in the form does not reset as expected, and sometimes fields intended for specific roles still appear even when the role has changed. Here’s a simplified version of my code: ```vue <template> <div> <select v-model="selectedRole" @change="onRoleChange"> <option value="admin">Admin</option> <option value="editor">Editor</option> <option value="viewer">Viewer</option> </select> <div v-if="selectedRole === 'admin'"> <input v-model="adminField" placeholder="Admin Specific Input" /> </div> <div v-if="selectedRole === 'editor'"> <input v-model="editorField" placeholder="Editor Specific Input" /> </div> <div v-if="selectedRole === 'viewer'"> <input v-model="viewerField" placeholder="Viewer Specific Input" /> </div> </div> </template> <script> export default { data() { return { selectedRole: '', adminField: '', editorField: '', viewerField: '' }; }, methods: { onRoleChange() { // Reset fields on role change this.adminField = ''; this.editorField = ''; this.viewerField = ''; } } }; </script> ``` When I change the role from 'admin' to 'editor', I expect the `adminField` to reset, but it sometimes retains the previous value. Additionally, if I switch back to 'admin' without refreshing, the `adminField` still displays the previous value, which causes confusion. I've also checked that the `onRoleChange` method is being called on the change event, and it appears to reset the fields as intended, yet the state does not seem to reflect this accurately. I've tried wrapping the `v-if` conditions in a computed property as well, but that didn’t resolve the issue. Could there be a reactivity issue at play here, or is there a better approach to handle conditional forms in Vue 3? Any help would be greatly appreciated! This is part of a larger service I'm building. My development environment is macOS. Any pointers in the right direction? This is for a application running on CentOS. This is my first time working with Javascript 3.9. What would be the recommended way to handle this?
