    copied!<p>I am trying to access a list of JSON objects (from mongo) in python to populate a dropdown list using flask templates. Subsequently, I need to access the selected item. I am having difficulty getting the list to populate. Here's my python code and template. Can anyone point me in the right direction? I have not been able to find good documentation on how to populate the dd list with these templates.</p> <p>PYTHON:</p> <pre><code>@app.route('/page', methods=["GET", "POST"]) @login_required def chooser(): # Option list returns a list of JSON objects option_list = get_options(g.user) # {u'_id': ObjectId('52a347343be0b32a070e5f4f'), u'optid': u'52a347343be0b32a070e5f4e'} # for debugging, checks out ok print option_list # Get selected id &amp; return it if request.form['submit'] == 'Select': optid = o.optid resp = 'You chose: ', optid return Response(resp) return render_template('chooser.html') </code></pre> <p>HTML TEMPLATE:</p> <pre><code>{% extends "layout.html" %} {% block content %} &lt;h2&gt;Chooser&lt;h2&gt; &lt;h3&gt;&lt;table&gt;&lt;form action="" method="POST"&gt; &lt;td&gt; &lt;label&gt;Select :&lt;/label&gt; &lt;select name="option" width="300px"&gt; {% for o in option_list %} &lt;option name="{{ o.optid }}" SELECTED&gt;{{ o.optid }}&lt;/option&gt; &lt;/select&gt; &lt;/td&gt; &lt;td&gt; &lt;input class="button1" type="submit" value="Select"&gt; &lt;/td&gt; {% endfor %} &lt;/form&gt;&lt;/table&gt;&lt;h3&gt; &lt;/div&gt; {% endblock content %} </code></pre>
