Front end entry form drop down field I'm trying to update a drop down field type on an entry using a front end form. However, the input is a hidden field (not a select)

This is the form code I have so far:

&lt;form method="post" accept-charset="UTF-8"&gt;
    {{ getCsrfInput() }}
    &lt;input type="hidden" name="action" value="entries/saveEntry"&gt;
    &lt;input type="hidden" name="redirect" value="questions/{{ selectedSession }}"&gt;
    &lt;input type="hidden" name="enabled" value="1"&gt;
    &lt;input type="hidden" name="sectionId" value="{{ question.sectionId }}"&gt;
    &lt;input type="hidden" name="entryId" value="{{ question.id }}"&gt;
    &lt;input type="hidden" name="fields[questionStatus][]" value="answered"&gt;
    &lt;input type="submit" value="submit"&gt;
&lt;/form&gt;


Where questionStatus is my dropdown field handle.
Any insight would be appreciated
Thanks

Update

I have ensured that the account's user type has the necessary permissions to perform this operation
I think you just need to get rid of the [] on the field name, so your field becomes:

&lt;input type="hidden" name="fields[questionStatus]" value="answered"&gt;


As long as the value is the same as the value in the dropdown, it should change.

I think the issue you are getting is because you are telling the field that its value is an array, where you just need to pass the actual value as a string and Craft will figure out the rest :)
