Chained Select field for Contact Form 7 is a feature in Contact Form 7 where the options in one dropdown field change dynamically based on the user’s selection in a previous field.

This creates a series of interdependent select fields, helping simplify the selection process by only showing relevant options. A common example is selecting a country, then a state/province, then a district, or choosing a car brand, then the model, then the production year.

How It Works

• • Dependent fields: Each select field is linked to the previous one. When the user chooses an option, the next field is automatically filtered to show only matching values.

  • Multiple Data Sources Supported:

    • CSV File: Load options from a CSV file using rows and columns to define relationships.

    • Database: Fetch options dynamically from your database (e.g., MySQL) using custom queries.

    • Manual Input: Manually enter your hierarchy (e.g., Brand → Model → Year) directly in the settings.

    • Google Sheets: Pull live data from Google Sheets to generate dynamic options.

Use Cases

• Filtering complex datasets: Helps users navigate large datasets without being overwhelmed.

• Real-world examples:

  • Country → State/Province → District

  • Car Brand (Toyota, Honda) → Model (Camry, CR-V) → Production Year

  • Department → Employee

  • Topic → Subtopic

Benefits

• Improved user experience: Users can complete forms faster and more efficiently.

• Higher performance: Reduces irrelevant options, allowing users to focus only on what’s necessary.

• Flexible: A versatile tool suitable for many types of forms and applications.
