I'm using a module for Odoo documents management, in the view of the main directory there is an one2many field for sub-directories and it point's to the same model so while creating it's open a wizard exactly like the form which it locates, I need to hide some fields form this wizard and add some new fields related to sub-directories only, how can I do that, this the code

 class Directory(models.Model):
_name = 'muk_dms.directory'
_description = "Directory"
_inherit = [
    'muk_utils.mixins.hierarchy',
    'muk_security.mixins.access_rights',
    'muk_dms.mixins.thumbnail',
]
_order = "name asc"
_parent_store = True
_parent_name = "parent_directory"
_parent_path_sudo = False
_parent_path_store = False
_name_path_context = "dms_directory_show_path"
#----------------------------------------------------------
# Database
#----------------------------------------------------------
name = fields.Char(
    string="Name", 
    required
    required=True,
    index=True)
is_root_directory = fields.Boolean(
    string="Is Root Directory", 
    default
    default=False,
    help="""Indicates if the directory is a root directory. A root directory has a settings object,
        while a directory with a set parent inherits the settings form its parent."""
        while a directory with a set parent inherits the settings form its parent.""")
root_storage = fields.Many2one(
    comodel_name='muk_dms.storage',  
    string
    string="Root Storage",
    ondelete='restrict')
storage = fields.Many2one(
    compute='_compute_storage',
    comodel_name='muk_dms.storage', 
    string
    string="Storage",
    ondelete='restrict',
    auto_join=True,
    readonly=True,
    store=True)
parent_directory = fields.Many2one(
    comodel_name='muk_dms.directory', 
    domain
    domain="""[('permission_create', '=', True)]""",
    context="{'dms_directory_show_path': True}",
    string="Parent Directory",
    ondelete='restrict',
    auto_join=True,
    index=True)

as it shown in above code the last field is get the data form the same model, how can i display wizard with different fields Thanks in advance,
