Available Filter Properties

When you reference a dropdown filter in inline queries using the {{filter_id.property}} syntax, the following properties are available:

​
.filter

Returns a complete SQL filter expression ready to use in WHERE clauses. Returns true when no value is selected.

​
.selected

Returns the selected value wrapped in quotes, suitable for SQL comparisons. Returns an empty string when no value is selected. Use with a fallback value.

​
.literal

Returns the raw unescaped selected value, useful for dynamic column selection or other non-quoted uses.

​
Example Usage

{% dropdown
  id="category_filter"
  data="products"
  value_column="category"
  title="Product Category"
/%}

```sql filtered_products
select * from products
where {{category_filter.filter}}
