SELECT_LIST_FROM_LOV Function

This function dynamically generates select lists from a shared list of values (LOV). Similar to other functions available in the APEX_ITEM package, these select list functions are designed to generate forms with F01 to F50 form array elements.

Syntax

APEX_ITEM.SELECT_LIST_FROM_LOV(
    p_idx           IN   NUMBER,
    p_value         IN   VARCHAR2 DEFAULT,
    p_lov           IN   VARCHAR2,
    p_attributes    IN   VARCHAR2 DEFAULT,
    p_show_null     IN   VARCHAR2 DEFAULT,
    p_null_value    IN   VARCHAR2 DEFAULT,
    p_null_text     IN   VARCHAR2 DEFAULT,
    p_item_id       IN   VARCHAR2 DEFAULT,
    p_item_label    IN   VARCHAR2 DEFAULT)
    RETURN VARCHAR2;
