Described are methods and systems for providing value help features to input fields. In response to a user selection of a condition type, an associated metadata is retrieved. Based upon the metadata, a user interface element comprising a static key and a dynamic key is generated. The dynamic key includes a name field and a value input field. Based upon the user interface element, a generic query including an input parameter node and a result node is generated. For the name field and the value input field of the dynamic key, a sequence number indicating an associated attribute group is extracted from the metadata. Based upon a field type of the value input field, the user interface element is bound to the associated attribute group indicated by the sequence number. Based upon the user entry received at the value input field, a corresponding value help feature is displayed.
