login

This is how you can redirect a user to a destination after login

If you want a default value disappering from your textfield e.g in a login- or search field you can add javascript to input tag. This is a customized login form to Drupal.

As you can see I changed the name on username field to xyz-name. In my case some script cleared username field, so I changed name and change it back on focus. Maybe there is some better way to do this.
