SEO Select Components - Documentation

Basic Select Usage

Overview

SEO Select provides two main implementation methods: the recommended slot-based approach using standard HTML option tags, and a fallback array-based method for dynamic content. Both methods support full keyboard navigation, form integration, and accessibility features.

Slot Method (Recommended)

The slot-based approach uses standard HTML <option> tags as children, providing semantic HTML structure and better SEO compatibility. This method maintains the original HTML form behavior while adding enhanced functionality.

💡 Uses standard HTML option tags with selected attribute support

Array Method (Fallback)

When slot content is not available or when options need to be populated dynamically through JavaScript, the array method provides a programmatic interface using the optionItems property.

🔧 Populated via JavaScript optionItems property - ideal for dynamic content

Keyboard Navigation & Accessibility

Full keyboard navigation support includes Tab for focus, Arrow keys for option navigation, Enter for selection, Escape to close, and Space for dropdown toggle. Screen reader compatible with proper ARIA attributes.

⌨️ Try Tab, Tab + Shift, Arrow keys, Enter, Escape - fully accessible navigation

Event Handling System

Comprehensive event system with custom events (onSelect, onDeselect, onReset) and standard form events (change, input). All events provide detailed information about the selection state and can be used for form validation and data processing.
