Django Select Option selected issue

Question

I tried to follow some examples on stackoverflow for option selected in select list but still, I could not get it work.

This is my code snippet

<select name="topic_id" style="width:90%">
    {% for t in topics %}
        <option value="{{t.id}}" {% if t.id == topic_id %} selected="selected" {% endif %}>{{t.title}}{{t.id}}</option>
    {% endfor %}
</select>

I took the topic_id from param['topic_id'] in views.py.

Thanks!

Answer 1

Instead of selected="selected" just use selected.

<option value="{{t.id}}"{% if t.id == topic_id %} selected{% endif %}>{{t.title}}{{t.id}}</option>

There can be two reason if it is not working:

• In topics there is no such topic whose id is equal to topic_id
• t.id and topic_id may be of different types. Convert topic_id to int

Answer 2

this worked for me

<select class="form-control" id="exampleSelect2" name="nivel">
                {% for key, value in types %}
                    <option value="{{ key }}" {% if institution.nivel == key %} selected {% endif %}>{{ value }}</option>
                {% endfor %}
</select>
