Hello Everyone

Suppose i want to hide CRM menu so what i done. See the Code

1) create one file in security folder [security/security.xml​]

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <data noupdate="0">

<record id="make_invisible" model="res.groups">
    <field name="name">Show Crm Menu</field>
</record>
<record model="ir.ui.menu" id="crm.crm_menu_root">
    <field name="groups_id" eval="[(5,ref('make_invisible'))]"/>
</record>

</data>

</odoo>

2) then add menu in your custom created module in xml file 

<menuitem id="crm.crm_menu_root" name="CRM" groups="make_invisible"/>

3) then add the security files in __manifest__.py

'depends': ['base', 'crm'], 
'data': [
    'security/security.xml',
    'security/ir.model.access.csv',
],
'installable': True,
'auto_install': False,
'application': True,

I Hope i will help you

Add a custom xml file to your custom modules and use the delete tag.

For example for the Human Resource menu item

<delete model="ir.ui.menu" id="hr.menu_hr_root"></delete>

Yes this is possible. If you made the custom XML's with the <menuitem> tags as well, just add the the groups-attribute to that tag, like so:

<menuitem id="myitem" groups="hr.hr_manager"/>

This way, only users that belong to the hr_manager group defined in the HR module will be able to see the menu. 

You can alternatively also add your own groups in your module. The syntax would not differ much, but you would not point to the original HR module for the group name.
