I get all the portfolios of the logged in user and populate the 1st select with those portfolios now I want to populate the 2nd select with the groups on the basis of 1st select, For-example if user select portfolio_1 all the groups in the portfolio_1 should be loaded in the 2nd select box.</p> <p>The 1st select with portfolios is:</p> <pre><code>&lt;select id="portfolios" name="portfolio" style="width: 200px; height:25px;"&gt; &lt;option selected="selected" value="default"&gt;Select Portfolio&lt;/option&gt; {% for portfolio in portfolios %} &lt;option value={{ portfolio.id }}&gt;{{ portfolio.portfolioName }}&lt;/option&gt; {% endfor %} &lt;/select&gt; </code></pre> <p>What I understand is I need to call an ajax function onchange of the 1st select in that ajax I need to send the selected portfolio id and find all the groups with that id and then return all those groups and update only the 2nd select box with those groups, </p> <p>I dont know how can I populate the 2nd select with the groups I will get</p> <p>any ideas?</p> <p>Thanks</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.
