Method and system for dynamic management of viewable digital contents (CD_ij), in which arranging a modular interface (11) comprising principal digital modules (Pi) and derived digital modules (Dij) extending prevalently in a first direction (d1); translating at least one of the principal digital modules (Pi) along a first path (t1) so that the principal digital modules (Pi) overlap at least partially; expanding the principal digital modules (Pi) along a second path (t2); selecting a viewable digital content; expanding the selected viewable digital content (CD_ij) along a third path (t3), determining at least a first derived digital module (Dij), in which translating at least one of the principal digital modules (Pi) along the first path (t1), expanding the principal digital modules (Pi) along the second path (t2) and expanding the selected viewable digital content (CD_ij) along the third path (t3) determine selective dynamic accessibility to the viewable digital contents (CD_ij) on the modular interface (11). A modular interface (11) for dynamic management of the viewable digital contents (CD_ij) is also described.
