Something like this jsfiddle demo?

HTML:

<textarea id="mytext"></textarea>

<select id="dropdown">
    <option value="">None</option>
    <option value="text1">text1</option>
    <option value="text2">text2</option>

    mydropdown.onchange = function(){
          mytextbox.value = mytextbox.value  + this.value; //to appened
         //mytextbox.innerHTML = this.value;
    }
