@Davor Hrg
Your solution wouldn't work because if you generate invisible content on the
server and then make it visible on the client using Javascript, then the
application won't work for people that have Javascript disabled. For me it is
an absolute requirement to have pages work without Javascript.
In my case I'm showing a couple of questions on the page. For each question it
is possible to add a note and to upload a file. Since adding a note or
attaching a file is the exception rather than the rule and since the textarea
and upload-field take up precious space and may even confuse users, we hide
those areas using Javascript and add a coule of icons for collapsing the areas.
This improves the user-experience for people that have Javascript enabled, but
still allows people without Javascript to see the areas and use their
functionality.
This is really a very common approach that is being used in several companies
I've worked for, especially for government work where it is essential users can
access the web applications without Javascript.
