Cascading ComboBox Using Vue ComboBox

Repository Description: A Vue.js project demonstrating cascading ComboBox components using Syncfusion, where dependent ComboBoxes populate based on parent selections.

Overview

Learn how to create a cascading ComboBox using Syncfusion Vue ComboBox. This project shows how to add multiple ComboBox components and populate dependent ComboBoxes based on parent selections—ideal for country-state scenarios and similar dependent dropdowns.

Prerequisites

• Node.js (v12 or higher)
• Vue CLI (v4 or higher)
• npm (v6 or higher)

Installation

Clone the repository:

git clone https://github.com/SyncfusionExamples/create-a-cascading-combo-box-using-vue-combo-box combobox-component
cd combobox-component
npm install

Running the Application

Start the development server:

npm run serve

Navigate to http://localhost:8080/. The app reloads on file changes.

How It Works

1. First ComboBox selection triggers an event
2. Selected value filters/fetches data for the second ComboBox
3. Second ComboBox updates its data source dynamically
4. Extend this pattern to multiple cascading levels
