Element's choices dynamically filtered by another

I am already working on a case where the 2nd (3rd, 4th, etc..) field is on another page.

So you pick an option, click 'next', and then the options on the 2nd page have filtered out the 'impossible' choices.

Your idea is almost the same, except it uses ahah/ajax to update the next form element instead of a 2nd page.

It may take some time to get around to it, but I think your idea is worth implementing too, and since the form generation and query stuff in Finder Wizard can be reused all that is needed is the javascript callback stuff to pull it all together.

Yeah it's not ready.

There is an ajax module which may help significantly in implementing this feature. Just thought i'd leave that info here for when I get to working on this.

I figure this issue will require
1) the completion of the wizard module
2) a way to go to the next page upon selecting an element in optionwidgets
3) ahah integration which is on the way

OK so I've got the Finder Wizard module working, and Finder now supports AHAH updating, so the theories and queries behind filtering one element by another are workable into something like this.

The differences would be
- Not to 'hide' the other elements on the page.
- To not use back/next buttons but rather to do an AHAH update everytime a choice is made

And possibly/optionally
- Choices on later elements affect earlier elements (Finder Wizard only filters the element choices as you go forward through the steps, this may need to filter both ways)

I still plan to finish this, I apologise for the delays.

In the meantime this may be useful if you want to implement something like this yourself?: http://www.interworksinc.com/blogs/scorrales/2009/08/07/limiting-options...

+1 Pretty advanced but I needed it a couple weeks ago

hi,

Sorry for re-opening this issue, but I didn't find how to filter another field this way. I presume it's postponed as indicated ?

Please don't change the issue settings.

There are now options for this at (element) -> choices -> reduce
This also facilitated the ability to load an element using ajax when the page finishes loading, so that's under (element) -> form element -> ajax
