    <p>I am trying to change 'inputs' in this demo to 'selects'. The demo works fine, which is at:</p> <pre> http://devblog.jasonhuck.com/assets/infiniteformrows.html </pre> <p>The problem with modified is is everytime you click on add new row, it loses previous row selection, what was selected.</p> <pre><code> &lt;html&gt; &lt;head&gt; &lt;title&gt;Infinite Form Rows&lt;/title&gt; &lt;script type="text/javascript" src="http://cachefile.net/scripts/jquery/1.2.3/jquery-1.2.3.min.js"&gt; &lt;/script&gt; &lt;script type="text/javascript"&gt; $(function(){ // start a counter for new row IDs // by setting it to the number // of existing rows var newRowNum = 0; // bind a click event to the "Add" link $('#addnew').click(function(){ // increment the counter newRowNum += 1; // get the entire "Add" row -- // "this" refers to the clicked element // and "parent" moves the selection up // to the parent node in the DOM var addRow = $(this).parent().parent(); // copy the entire row from the DOM // with "clone" var newRow = addRow.clone(); // set the values of the inputs // in the "Add" row to empty strings $('input', addRow).val(''); $('select', addRow).val(''); // replace the HTML for the "Add" link // with the new row number $('td:first-child', newRow).html(newRowNum); // insert a remove link in the last cell $('td:last-child', newRow).html('&lt;a href="" class="remove"&gt;Remove&lt;\/a&gt;'); // loop through the inputs in the new row // and update the ID and name attributes $('input', newRow).each(function(i){ var newID = newRowNum + '_' + i; $(this).attr('id',newID).attr('name',newID); }); // loop through the inputs in the new row // and update the ID and name attributes $('select', newRow).each(function(i){ var newID = newRowNum + '_' + i; $(this).attr('id',newID).attr('name',newID); }); // insert the new row into the table // "before" the Add row addRow.before(newRow); // add the remove function to the new row $('a.remove', newRow).click(function(){ $(this).parent().parent().remove(); return false; }); // prevent the default click return false; }); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form&gt; &lt;table id="tabdata"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;Row&lt;/th&gt; &lt;th&gt;Cell 1&lt;/th&gt; &lt;th&gt;Cell 2&lt;/th&gt; &lt;th&gt;Cell 3&lt;/th&gt; &lt;th&gt;&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;&lt;a id="addnew" href=""&gt;Add&lt;/a&gt;&lt;/td&gt; &lt;td&gt; &lt;select name="1_0" id="1_0" style="width: 160px;"&gt; &lt;option value="option1"&gt;Option 1&lt;/option&gt; &lt;option value="option2"&gt;Option 2&lt;/option&gt; &lt;option value="option3"&gt;Option 3&lt;/option&gt; &lt;option value="option4"&gt;Option 4&lt;/option&gt; &lt;option value="option5"&gt;Option 5&lt;/option&gt; &lt;/select&gt; &lt;/td&gt; &lt;td&gt;&lt;input id="n0_2" name="n0_2" type="text" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input id="n0_3" name="n0_3" type="text" /&gt;&lt;/td&gt; &lt;td&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;input id="go" name="go" type="submit" value=" Save " /&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
