Creating and Expanding Entry Form

[George1111]

Preferably in ASP using HTML, I am trying to create a page which will provide a series of headings, which when clicked expand and show a series of options with Entry boxes along side (the resultant form will be "posted")

Any ideas how to achieve this please

example

HEADING1
HEADING2
HEADING3
HEADING4
HEADING5

When HEADING2 is Clicked Show

HEADING 1
HEADING2
subheading1 [textBox]
subheading2 [textBox]
subheading3 [textBox]
subheading4 [textBox]
subheading5 [textBox]
subheading6 [textBox]
subheading7 [textBox]
HEADING3
HEADING4
HEADING5

if I then click on HEADING2 then it will show

HEADING1
HEADING2
HEADING3
HEADING4
HEADING5

ie, the expanded section is un-expanded

Sorry if this is very basic - I am just a learner
