Body
<p>I have a Javascript like this:</p> <pre><code><script language="javascript"> function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length; var row = table.insertRow(rowCount); var colCount = table.rows[0].cells.length; for(var i=0; i<colCount; i++) { var newcell = row.insertCell(i); newcell.innerHTML = table.rows[0].cells[i].innerHTML; switch(newcell.childNodes[0].type) { case "text": newcell.childNodes[0].value = ""; break; } } } var showMode = 'table-cell'; if (document.all) showMode='block'; function toggleVis(btn){ btn = document.forms['tcol'].elements[btn]; cells = document.getElementsByName('t'+btn.name); mode = btn.checked ? showMode : 'none'; for(j = 0; j < cells.length; j++) cells[j].style.display = mode; } </script> </code></pre> <p>The following is HTML for show/hide the columns and insert new row:</p> <pre><code><body> <form name="tcol" onsubmit="return false"> Show columns <input type=checkbox name="col1" onclick="toggleVis(this.name)" checked> 1 <input type=checkbox name="col2" onclick="toggleVis(this.name)" checked> 2 <input type=checkbox name="col3" onclick="toggleVis(this.name)" checked> 3 </form> <input type="button" value="Insert Row" onclick="addRow('dataTable')"> <table id="dataTable"> <tr> <td name="tcol1" id="tcol1"><input type="text" name="txt1"></td> <td name="tcol2" id="tcol2"><input type="text" name="txt2"></td> <td name="tcol3" id="tcol3"><input type="text" name="txt3"></td> </tr> </table> </code></pre> <p>I can insert row, but only the first row's column can be hidden. Is it because of the input fields' attributes? If yes, how do I add tag attribute into new row? Please help me out on this. Thanks.</p>

Guidance

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.
