Question

I have a form:
http://fiddle.jshell.net/eJ2kS/
I want to have the label and text input on one line and the button to be appended to the text input but the documentation is a little vague about appending buttons:

Do you opt for THIS?

If so, then the code shall be…

<form id="signup" method="post" action="/signup" class="form-horizontal">
                    <legend>Sign Up</legend>

                    <div class="control-group">
                        <label for="appendedInputButton" class="control-label">User Name</label>
                        <div class="controls">
                          <div class="input-append">
                            <input type="text" size="16" id="appendedInputButton" class="span2"><button type="button" class="btn">Check Availabilty</button>
                          </div>
                        </div>
                     </div>
                </fieldset>
            </form>

I think I’ve updated your fiddle… RIGHT HERE.
