I have a tab in my salesforce instance named as RelationShip Modules. I want to add custom functionality on this tab, when I click on tab, it should display sub-menu with Modules Names Leads, Accounts, Contacts etc.
When I click on one value i.e. module name like Leads, it should open its list view. then all other functionality should be same. I want to get something like this:
Here when I click on Tab Client Relationships, It should show me menu same as shown in figure above.
Is it possible in salesforce by using Visualforce or any thing else?
Any help will be appreciated.
