[html-formfu] Bootstrap forms again...

[Nigel Metheringham]

Like various other people, I hit the difficulty lining up FormFu's form 
generation and Bootstrap.

I did get it working OK with tt based HTML generation, and actually very 
minor changes - although I have effectively hardwired to horizontal 
forms - see http://twitter.github.io/bootstrap/base-css.html#forms - and 
inline checkboxes.

However I think if the class addition was removed from the form tag, the 
horizontal forms would revert to "normal" even with the additional label 
markup, and the inline checkboxes are similarly a case of just change an 
attribute.

So, the only changes from the default form tt files were:-
   - start_form - tweaked the classes on the form tag
     possibly doable with just attributes

   - textarea_tag - wrapped an extra div around for use with
     ckeditor (unrelated to bootstrap really)

   - field - the main label/control-group changes for bootstrap

   - checkboxgroup_tag - rework for inline checkboxes


I've not spent a batch of time profiling speed with this - its good 
enough for my use.  The tt could be made faster by reusing the tt object 
I already have in place for the app - in fact I suspect I could probably 
do this by changing the
   [% form.render %]
in those templates to something that does form.render_data and then just 
calls PROCESS on the templates (would then get all the templates into my 
cache too).

In terms of just making a new bootstrap renderer within the classes, it 
should be easily doable by having it use the string renderer everywhere 
except the 4 places mentioned above.

The form definitions have also changed slightly - but only in that I 
have added some class attributes to some elements (mainly to force them 
wider - attributes => {class => 'span6'} - or to make the form buttons 
prettier.

	Nigel.
