Value from/to for one field

The “Value from/to for one field” filter rule (package filter_fromto) filters items based on a value range for a single numeric or text-based attribute. Visitors can enter a “from” value, a “to” value, or both in the frontend. The filter rule returns all items whose attribute value falls within the specified range.

Typical use cases: Price filters (price from X to Y), size or age specifications, or general numeric range filters.
