Can I hide a column in displaytag using media='none'
displaytag, jsp
Solution
`media='none'` is same as `media='abc'`.
Reason it finds 'abc' (or any string) as [mymedia]
You should Use
<display:column property="index" title="" class="hidden" headerClass="hidden" />
And in your `CSS` file.
.hidden {
display: none;
}
Problem
Can i hide a column in displaytag using `media='none'`? Will there be any other consequences due to this as am using the value from the hidden column in another column of the displaytag as a parameter to a hyperlink. I succeeded in hiding the column but get the foll: warning in the server logs W org.displaytag.tags.ColumnTag setMedia Unrecognized value for attribute "media" value="none" I tried using class as hidden but it didn't workout so i went ahead with media as none and it worked. ``` <table border="1" width="100%" align="center" cellpadding="0" cellspacing="1" class="table_main"> <display:table
