I have a sharepoint 2007 list and it has 6 site columns, want to have two modes of newform.aspx page. When user clicks on Newitem, it should display only 3 site columns and there should a link to the advanced mode, when user clicks on the advanced mode link it should display all those 6 site columns and corresponding column values should be pre-populated if user already enters some information in the simple mode. And user should be able to go simple mode from the advanced mode.
I also want to display current user's name on the label is in the NewForm.aspx page
How it can be achieved? Dowe need to write some kind of javascript?
