Freeform Pro Composer Templates - add class to input/select/checkboxes

Question

Is there an easy way to apply classes to Freeform Pro form elements in composer mode?

I have gone through several SO posts (& blog posts including this helpful one) however haven't been able to find a solution to cover all elements.

The general suggestion appears to be:

Replace

{composer:field_output}

With

{freeform:field:{composer:field_name} attr:class="form-control"}

Which works well until you get to <select> & other HTML elements:

Note: The orange highlight is where a select field type should be and the red is a random tag that I can't seem to work out where it's coming from...

The only way I can get all elements to display correctly is by using the standard syntax "{composer:field_output}" and then jQuery to add classes to elements:

//jQuery
$('.composer-form input[type="text"],.composer-form select,.composer-form textarea').addClass("form-control");
$('.composer-form input[type="submit"]').addClass("btn btn-primary");

If there isn't an easy way to apply relevant classes to elements using conditional statements, I will stick with the jQuery option however I really hope it's something simply I am missing in my composer template (see below for the template code).

Any help, advice or insight will be greatly appreciated.

        {/composer:columns}

    {/composer:rows}
{/composer:page}
</div>

It should be done like so:

{composer:fields}
                {if composer:field_output}
                    {if composer:field_type == 'nonfield_title'}
                        <h2>{composer:field_output}</h2>
                    {if:elseif composer:field_type == "text"}
                        <fieldset>
                        <label class="field_label no-sidebar" {if composer:field_name != ''}for="{composer:field_name}"{/if}>
                            {composer:field_label}
                            {if composer:field_required}<span class="required" required aria-required="true">*</span>{/if}
                        </label>
                        <input type="text" class="input" name="{composer:field_name}" placeholder="{composer:field_label}"></fieldset>
                    {/if}
                    {if:else}
                        <fieldset>{composer:field_output}</fieldset>
                    {/if}
                {/if}
{/composer:fields}

You could always add some extra CSS to target input fields, for instance:

.composer-form input[type='checkbox'] { /* your styles */ }
.composer-form input[type='text'] { /* your styles */ }
