Try the following.
<html:select property="category" style="width:155px" tabindex="12">
1opt<html
ption value="" >- - - -Select- - - - </html
ption>2opt<html
ption value="...">...</html
ption>
3opt<html
ption value="...">...</html
ption>
4opt<html
ption value="...">...</html
ption>
5opt<html
ption value="...">...</html
ption>
</html:select>
Observe the above code.Don't provide the value to 1opt(first option).It'll work fine.
