How to add tooltips to dropdown choices

[Lorne Malvo <ca...@gmail.com>]

Is there a simple way to insert a "title" HTML attribute into each option of
a DropDownChoice, in order to display a different tool tip with each choice?

I tried doing it simply by adding HTML in a ChoiceRenderer, but could not
get Wicket to not escape the HTML (can't call setEscapeModelStrings(false))
on a DropDownChoice. 

I also tried this...
https://stackoverflow.com/questions/12234738/wicket-dropdownchoice-titles-tooltips-for-options
... but it didn't work for me. First, that method was always calling
toString() on my model object to display the option, which is not what I
wanted, and I couldn't see a way to make that subclass non-generic.
Secondly, even if I had had the aforementioned problem, the tooltip didn't
even show up. 

Anyway to do this simply?

Thanks in advance!

Hi,

You can override #setOptionAttributes() -
https://github.com/apache/wicket/blob/77d8bf32d2063ac0174fc383da81ac2d6bcc482b/wicket-core/src/main/java/org/apache/wicket/markup/html/form/AbstractChoice.java#L457
