This has maybe been requested before, but i could not find it in the issue tracker...

The multi select option is a really cool feature that would be very handy for CCK multiselect fields. Anybody who knows how to start here?

Title: Support for CCK select fields » New mode that doesn't support hierarchies, but does allow usage of the dropbox

You have to implement the HS API for each hierarchy you want to use HS for. It cannot be used in a generic way.

What I could do, is allow for a "non-hierarchical HS mode", which just provides you with the ability to use the dropbox, and doesn't support hierarchies. Basically you only have to implement the hook_hierarchical_select_root_level() hook for that, and all other hooks should pretend that there are no child levels.

This will be a 6.x only feature, probably.

P.S.: support for the Location field is planned, and will be probably be added in July.

Hi Wim, thanks for your help.

I tried to get my head around this. How and where do i start? Can i just place my code in a custom module?

Do i just need:
hook_hierarchical_select_root_level()

hook_form_alter() (for changing the type to "hierarchical_select") or would i rather use hook_hierarchial_select_form_alter($form_id, &$form)

I'd be happy to write up a tutorial once I figured that out for myself.

1) Read API.txt's "hooks" section.
2) Look at the modules/views_taxonomy.module file for an example that's pretty close to what you will be doing.
3) You need to implement root_level(), but also all other, non-optional hooks, most will be super easy though.

Sorry, I'm having a bit of a difficult time trying to follow the thread of activity here, I couldn't draw a conclusion.

Is it possible to enable HS Flat List for a CCK multi-select box? If so, please excuse my ignorance but, is there a not-so-dev explanation as to how to do so?

TIA
