Example​

    { id: "status",     label: "Status",     type: "text" },
    { id: "age",        label: "Age",         type: "number" },

  ];
</script>

<FilterQuery {fields} />

Details​

The fields prop defines which fields users can reference in a query. Each field includes an id, label, and type that determines how the value is interpreted.

The fields enable several features of the FilterQuery component: autocomplete suggestions, syntax highlighting for field names, and correct parsing of the query into a structured filter object. The labels are shown to users in the input and dropdown, while the corresponding IDs are used internally in the parsed value.

If no fields are provided, the input behaves like a plain text search and advanced query features such as autocomplete and highlighting are not available.
