Filter custom fields four ways
Pick the module that fits your data — each one works with any custom field.
Checkbox
Let visitors tick one or more values of a custom field — perfect for fields with a set list of options, like brand, material, or number of bedrooms.
Dropdown
Show a custom field’s values in a compact dropdown — great when there are many options or when you want to save space in the filter.
Search
Add a search box tied to a specific custom field, so visitors can type to find matches within that field — like searching an SKU, model, or ISBN.

Range Slider
For number-based custom fields — price, mileage, square feet, weight — give visitors a slider to filter by a minimum and maximum value.
Built for any kind of site
If it’s stored as a custom field, visitors can filter by it.
Find the right home
Filter listings by the details that matter — stored as custom fields on each property.
Shop by specs
Let buyers narrow by the numbers and options that define each vehicle.
Filter by product data
Use WooCommerce product fields to filter by anything beyond the standard attributes.
