    <p>I have two dropdown lists. If the user only selects something from one selection box, I want to re-render the page where it has the same dropdown lists, except the one that was selected shows the previous selection instead of the default selection. </p> <p>the html looks like</p> <pre><code>&lt;div&gt; &lt;select name = "menu" value = "{{menu}}"&gt; &lt;option value = "selected"&gt;select something&lt;/option&gt; &lt;option value = "a"&gt;a&lt;/option&gt; &lt;option value = "b"&gt;b&lt;/option&gt; &lt;option value = "c"&gt;c&lt;/option&gt; &lt;/select&gt; &lt;/div&gt; &lt;div&gt; &lt;select name = "location" value = "{{location}}"&gt; &lt;option value = "selected"&gt;select something&lt;/option&gt; &lt;option value = "d"&gt;d&lt;/option&gt; &lt;option value = "e"&gt;e&lt;/option&gt; &lt;option value = "f"&gt;f&lt;/option&gt; &lt;/select&gt; &lt;/div&gt; </code></pre> <p>the python looks like menu = self.request.get('menu') location = self.request.get('location')</p> <pre><code> if menu!="selected" and location!="selected": d = Delivery(parent = delivery_key(), menu = menu, location = location) d.put() deliverystatus = "success" self.render('page.html', deliverystatus = deliverystatus, menu = menu, location = location) else: error = "please select something from both lists" self.render("page.html", menu = menu, location = location, error = error) </code></pre> <p>When there is an error and I rerender the page I get "select something" as the default in both boxes. How do I change this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
