This feature does not rely on external plugins and is available through the theme's built-in modules.
Why Add Article Filtering
When a website becomes increasingly rich in content, a simple pagination display may no longer be able to satisfy the visitor's need to find it quickly. The article filtering function is particularly suitable as it allows quick switching by article categories, making it easier for visitors to find the information they need:
- technical categoryblog (loanword)(e.g., front-end, back-end, tool categorization)
- Brand information pages (e.g. events, products, dynamic categories)
- Multi-topic blogs (e.g. travel, food, photography, etc.)
