Hello,
I need to dynamically hide and unhide a selection box based on the value
selected in the first selection box. So if a user selects "a" in
selection box, element id2 should be visible else it should remain
hidden. I can use
document.getElementByI("id2").style.visibility="visible" to make it
visible and document.getElementById("ed1").style.visibility="hidden"; to
make it disappear. The problem when element id2 disappears, it still
keeps space there and it makes the form look bad. Is there a way to
dynamically remove the space it occupies?
.......
<tr id="id1">
<td>
<select name="first" onchange="check(this)">
<option>a</option>
<option>b</option>
</select>
<td>
</tr>
<tr id ="id2" style="visibility:hidden";>
<td>
<select name="second">
<option>c</option>
<option>d</option>
</select>
<td>
</tr>
..............
rest of the form....
Thanks a lot,
Roland
