disable/enable form elements

[SgtBadass]

I have a form which has four menu lists. Depending on the state of the first one, the other three will be disabled. i.e. if they select 'FAQ' from the first drop down, they don't need to enter anthing in the other three so they should be disabled. Is this possible?

yes
there is an attribute called "disabled". So you can write :
document.my_form_name.my_element_name.disabled = "true";
