I am trying to integrate twitter bootstrap into my app. However I noticed the behavior of my app is different from the twitter bootstrap showcase…
I am in reference to the Base CSS/ form/ Validation states section.
For instance, the following
<div class="control-group">
<label class="control-label" for="email">Email</label>
<div class="controls">
<div class="input-prepend">
<span class="add-on">@</span> <input type="text" name="member.email" value="" id="email" autofocus="autofocus" />
</div>
</div>
</div>
does not render inline but instead as follows:

I am not sure what I got wrong. Can anyone please help?
The example you give is from the “Preppended and Appended Inputs” section and it does not include a label in the example. However, assuming that by “render inline” you mean have the label adjacent to the input control, that can be achieved using the
form-horizontalclass on the form itself.
