Large forms are slow on the iPad
- Forms with many inputs (600+ in my case) become extremely unresponsive on an iPad, up to the point where it can take several seconds for a control to respond to touch commands.
- This is true for both iPad 1 and iPad 2 models.
- While certain CSS styles can lead to performance issues Show archive.org snapshot , removing those styles won't help if the form simply is very large.
- A workaround is to only show a limited number of form inputs at the time, e. g. by toggling groups of form elements accordion-style. Hidden form elements do not slow down the iPad.
