How to get value from dropdown list

I'm trying to get value from dropdown box into variable and then store it. I'm new to Flask and cant find anything in the documents about it. But I dont know how to get the value from dropdown list with request.form or any other why in that matter.

My flask code in app.py 

@app.route('/add', methods=['POST'])
def add_entry():
    if not session.get('logged_in'):
        abort(401)
    title = request.form['title']
    link  = request.form['link']
    shown  = request.form['shown']

    #I hardcoded the id here too see basic function.

    kate = Category.query.filter_by(id = 2).first()
    add_into = Entries(title, link, shown, kate)
    db.session.add(add_into)
    db.session.commit()

And here is the html for it.

<form action="{{ url_for('add_entry') }}" method=post class="add-entry custom">
  <dl>
    <dt>Title:
    <dd><input type=text size=120 name=title>
    <dt>Link:
    <dd><input type=text size=120 name=link>
    <dt>Shown:
    <dd><input type=text size=120 name=shown>
    <label for="customDropdown">Category</label>
    <select style="display:none;" id="customDropdown">
      {% for c in cate %}
        {% if c.id == 1 %}
          <option id="{{ c.name }}" name="{{ c.name }}" SELECTED>{{ c.name }}</option>
        {% else %}
          <option>{{ c.name }}</option>
        {% endif %}

      {% endfor %}
    </select>
    <dd><input class="success button" type=submit value=Post it!>
    </dl>
</form>

A select tag, like an input tag, needs a "name" attribute on it if you wish to have the value passed as form data.

<select name="name" style="display:none;" id="customDropdown">

Now, you should be able to access it through request.form['name'] as you have been your input elements.
