An electronic device includes a first operation member for changing a set value of an allocated function item, and a second operation member for changing a function item allocated to the first operation member, and registers a set of function items to be allocated to the first operation member. The set includes a standard function that is allocated to the first operation member before the second operation member is operated, and the electronic device controls switching among function items to be allocated to the first operation member based on whether the standard function is an invalid function and on the number of function items included in the registered set, the switching being performed in response to an operation performed on the second operation member, the invalid function disabling changing of the set value by the first operation member.
