    <p>I have the following code with the logic I want as follows:</p> <ol> <li>A user can not select a sport twice. A user may have sports saved in the database and with that in mind, the database records will be loaded and displayed and the user is allowed to add additional sports as longer as they do not appear in the list. Right now I have set Baseball as coming from the database but when I select it again, my logic is allowing the user to add it again. What I am doing wrong?</li> </ol> <p>JSFIDDLE: <a href="http://jsfiddle.net/Jrqqq/" rel="nofollow">http://jsfiddle.net/Jrqqq/</a></p> <pre><code> var allVals = [{ id: 1, value: "Baseball"}]; $.each(allVals, function (k, v) { $("#results").append("&lt;label class=\"wList\"&gt;&lt;input checked=\"checked\" class=\"wList-chk\" name=\"wList[]\" type=\"checkbox\" value=\"" + v.id + "\"&gt;" + v.value + "&lt;/label&gt;"); }); $(function () { var sports = [{ id: 1, value: "Baseball" }, { id: 2, value: "Soccer" }, { id: 3, value: "Basketball" }, { id: 4, value: "Volleyball" }, { id: 5, value: "Tennis" }, { id: 6, value: "Running" }, { id: 7, value: "Swimming"}]; $("#sports").autocomplete({ source: sports, select: function (event, ui) { if ($.inArray(ui.item.id, allVals) == -1) { allVals.push(ui.item.id); $("#results") .append("&lt;label class=\"wList\"&gt;&lt;input checked=\"checked\" class=\"wList-chk\" name=\"wList[]\" type=\"checkbox\" value=\"" + ui.item.id + "\"&gt;" + ui.item.value + "&lt;/label&gt;"); $('input.wList-chk[type="checkbox"][value="' + ui.item.id + '"]').parent().effect('highlight', {}, 1500); ui.item.value = ""; } else { ui.item.value = ""; $('input.wList-chk[type="checkbox"][value="' + ui.item.id + '"]').parent().effect('highlight', {}, 1500); } } }); }); $(document).on("change", ".wList-chk", function () { if ($(this).attr('checked')) { return; } else { var thisVal = $(this).val(); var index = $.inArray(thisVal, allVals); allVals.splice(index, 1); $(this).parent('.wList').remove(); } }); </code></pre>

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.
