If I'm getting you correctly - you want an final option on the select's options list with "create new one"?
Than you should give it a unique value like "createcategory" and put onchange event on that select box

<select name="..." onchange="javascript:checkSelect(this.value);">

As you can see - I called the javascript function checkSelect that you should create with somethis like that:

function checkSelect(val)
{
    if(val == "createcategory")
        document.getElementById('the_input_id').disabled = false;
    else
        document.getElementById('the_input_id').disabled = true;
}

What I did in this function is to check on every change of the select-box if the value of the selected option is "createcategory", and if so - I'm setting the text input disabled to false, so it would work, otherwise - I'm setting it again to true
