[web2py] Bootstrap and custom forms and widgets

[Matt]

Hi Everybody,

I'm using bootstrap for a project with web2py.

I want to create forms that mirror the standard approach taken by the 
bootstrap framework.

They wrap each "control" like so:

  <div class="control-group error">
        <label class="control-label" for="inputError">Input with 
error</label>
        <div class="controls">
          <input type="text" id="inputError">
          <span class="help-inline">Please correct the error</span>
          <p class="help-block">A comment for the field goes here.</p>
        </div>
      </div>

Since this is custom code I using form.custom and form.fields for output 
the HTML myself.

One small problem I've run up against in that when I do the following:

{{= form.custom.widget.full_name }}

If there is a form _error_ the following is output:

<input class="invalidinput" id="xyz_full_name" name="full_name" type="text" 
value="">
*<div class="error" id="full_name__error">please enter their full name</div>
*
*
*
Is there anyway to suppress the div or change it so that it can become

*<span class="help-inline">please enter their full name**</span>*
*
*
Instead?

Any help or suggestion for this would be greatly appreciated.

Thanks in advance,
Matt
