Re: Hybrid palette with DropDownChoice and ListView
Great, I'm still getting NonUniqueObjectExceptions when I save.

Re: Hybrid palette with DropDownChoice and ListView
Thanks for the suggestions. Regrettably the spec requires a vertical list of labels and specifically not a multi choice list as used in the extensions Palette component otherwise yes it would be trivial to make the right hand side a one row drop down as you mention... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Hybrid-palette-with-DropDownChoice-and-ListView-tp4664445p4664448.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Btw, Select2 demos are at: http://ivaynberg.github.io/select2/ Its Wicket integration at: https://github.com/ivaynberg/select2 That's Igor's baby (you might have seen Igor's name in Wicket's API JavaDocs :) On Thu, Feb 13, 2014 at 11:34 AM, Paul Bors wrote: > I don't think you need to go nuts and worry much about a ListView.

Re: Hybrid palette with DropDownChoice and ListView
I don't think you need to go nuts and worry much about a ListView. Use a Select2 instead of the drop-down and have a custom panel instead of the plain old option. You can place an Add button or something or better yet, check boxes and then you won't need the second list. Suppose you do stick to old HTML components like a DropDown and a ListView. First off, get off the list view and use a multiple Select. Take a look at how the wicket pallet is done at: http://www.wicket-library.com/wicket-examples/compref/wicket/bookmarkable/org.apache.wicket.examples.compref.PalettePage All you would have to do is change the left available multi select with your drop down. Now, I would recommend using jQuery UI's widgets since they are easier to use and more fun to work with (both for the developer and the application user): http://jqueryui.com/demos/ Have fun!

Hybrid palette with DropDownChoice and ListView
Hello, I'd like to create a hybrid 'palette'. First there's a DropDownChoice with an 'Add' link and next to this a vertical list of selected items, each with a 'remove' link. Of course, adding an item removes it from the DropDownChoice and adds it to the list and vice-versa for item 'removal'. I have already started but I fear that this is probably going to be fairly complicated as it involves using ListViews in a form and DropDownChoice customisation so any pointers to get me going would be most appreciated. I'll post some code once I have something vaguely functional!
