Login menu functionality

[RaoBhethanabotla]

Before a user logs in, Login will be a simple option on the top menu bar. Once user clicks on Login, a Login page is shown to register a new user or allow the login of an already registered user.

Once user logs in, we do the following changes to this menu option:

• Show a small user image and user's first name instead of the text "Login". This will be a pull down menu.
• One of the options is Logout. When clicked on this we logout from our app.
• Profile will be another option in the drop down menu. When clicked on Profile, we show a page to allow this user to change all his/her changeable attributes. User can change one or more attributes or simply click on Cancel to go out of this page.
• We also provide support to upload an image of this user. Once uploaded, we need to store this image on S3 and show it on the menubar.
