Hi Odooers,

I like to add my custom modules (e.g., Module1, Module2, Module3) under the left side searchpanel 'CATEGORIES', for example 'My Modules' after 'Sales'. How can I do it?

I added a record in 'odoo\addons\base\data\ir_module_category_data.xml' file, but do not know how to upgrade this main UI. another question is how these modules are categorized? 

The bottom picture was captured by clicking 'Manufacturing'. Five modules in this category and they have different 'Category' if clicking "Module Info'
