Query Condition Filter only where get var has value

In the Dreamweaver version of Query builder in the where tab one could select an additional field below the field selection that meant it will show all the records but filter only when the condition set had a value. I cannot remember what this field was called… I think it was “Condition” actually. How do I do this with Wappler query builder? in other words, how do I let the condition trigger only if it has a value?
