如何在Java-Wicket中为组合框项目设置ARIA HTML标签？

Question

I need to add tag 'role="menuitem"' to items generated by Wicket in a drop-down field. I believe that tags for the combo-box itself can be set with onComponentTag, but I have no idea whether it could be applied to the menu items ( <ul><li><a> ...) themselves.

as said by oh-god-spiders DropDownChoice is designed to work with <select> and <option> tags. For a ARIA menu componet ListView might be a better choice. In any case, if you want to enrich DropDownChoice options you could override setOptionAttributes method and add the desired attribute. For example:

@Override
protected void setOptionAttributes(AppendingStringBuffer buffer, E choice, int index, String selected)
    {
        super.setOptionAttributes(buffer, choice, index, selected);
        buffer.append("role=\"menuitem\" ");
     ...
