The validation error in question is: "Error: Element option without attribute label must not be empty." There seems to be little to no human-readable documentation for that particular error, but it seems to mean that these are invalid: <option></option> <option value=""></option> This is valid for some reason, but doesn't appear to be a functional improvement: <option label="foo"></option> The "label" attribute for <option> isn't even supported by Firefox.
<option value=””> </option> <option value=””>Enter something meaningful</option> (where the phrase is descriptive of what is expected, or what nothing really means in this case)
The simple answer is to use
<option value=””>Enter something meaningful</option>
Like this: <option value=””> -- Choose -- </option> Unfortunately the situation isn't always simple, as with Bug 3311, "Statistical reports should error if row and column aren't selected" https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=3311 The solution offered by the patches, while correct, may make the form harder to use because of visual clutter. I think it would be interesting to learn what benefits there might be to the various options for differently-abled users such as the visually impaired. -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
