Select components do not allow setting attributes and JavaScript events on
<option /> tags
------------------------------------------------------------------------------------------
Key: WW-3209
URL: https://issues.apache.org/struts/browse/WW-3209
Project: Struts 2
Issue Type: Improvement
Components: Other
Affects Versions: 2.1.7
Reporter: Tim Stavenger
Priority: Minor
The combobox, select, optiontransferselect and any other tag that uses the
<option /> or <optgroup /> tags do not allow you to set any additional
attributes or JavaScript events besides the value posted back to the server and
the value displayed to the user.
I had a scenario where the client wanted a hover to appear for each option in a
multi-select component. I could have used the title attribute or the
onchange/onclick events of <option />, but couldn't because Struts didn't
support them (at least without modifying Struts). I ended up with a different
implementation that listened for onchange and onclick events for the <select />
tag. It works, but isn't exactly what the user wanted. I could also have just
manually used the <select> and <option> tag, but would have lost everything
else Struts provides.
See http://www.w3schools.com/tags/tag_optgroup.asp and
http://www.w3schools.com/tags/tag_option.asp for the available attributes and
events.
