In Sharepoint, I need modify a new item form of a list to make a field visible/invisible when a check box is selected:
For example:
There is a checkbox field called "Is XYZ affected?"
When a user selects this field, it will make a hidden field visible "Impact details:"
If "Is XYZ affected?" field is not checked, then "Impact details:" field is invisible.
This is easy to do it in html using javascript, how do I do it on Sharepoint?
Thanks!
