override selection for model

[zaxarhic2134]

I have a problem with select overriding in SelectMultipleField, I have a model Variable:

class Variable(Base):
    tablename = 'variable'
    id = Column(Integer, primary_key=True)
    connection_id = Column(Integer, ForeignKey('connection.id'))  # предполагается наличие связи
    variables = Column(ARRAY(String))
    hierarchy = Column(JSON)
    selected_variables = Column(ARRAY(String))
    selected_hierarchy = Column(JSON)
    connection = relationship("Connection", back_populates="variable")

And the model for sqladmin:

class VariableAdmin(ModelView, model=Variable):
    column_list = ['id', 'connection_id', 'variables', 'selected_variables']

If you do not override the Variables field, SelectMultipleField will be implemented

And I would like to make a similar selection for the selected_variables field from the existing Variables list

I tried to add a Varialbes selection via form_args but it didn't work, how can I implement this and if possible how can I handle this selection so that the selected_hierarchy field displays data depending on the selection
