I do have a solution for that called SimpleTreeDropdownField. I thought I bundled it with the code, but it looks like I overlooked it. I'll add it in as soon as I can.

SimpleTreeDropdownField is now bundled with the dataobject_manager module. Works like this:

new SimpleTreeDropdownField('RelationshipID', 'Title', 'ClassName');

The third argument, $sourceClass, defaults to "SiteTree", so to get a hierarchical dropdown of your site, just do SimpleDropdownField('Name','Title');

For a list of your assets structure, you could do:

SimpleTreeDropdownField('FolderID','Choose a folder','Folder');

I'll add "indentCharacter" as the next argument. Right now it's just two spaces. Seems good enough. Also, seems like it could use a filter and order clause.

Anyway, let me know how that gets you started.

UncleCheese, nice work. I've watched your videos and things are looking great. I myself am interested in an ImageDataObjectManager. I do not need the image gallery, but do need the data object manager (with the image preview and what not). The reason I do not need the image gallery portion is I plan to use the images in a slideshow page type that I have created. Currently I have used he CTF for my data management, but it is not sufficient (as you know). I am curious if waiting to see what ModelAdmin brings to the mix. Anyway, you seem very active, and I look forward to working with your modules. Also, how are the doc pages coming?

Thanks, Aram,

And just for clarity, the repo is at http://carlinowebdesign.svn.beanstalkapp.com/modules/trunk/dataobject_manager

@drye: The ImageDataObjectManager should be just what you need. I built it for exactly that purpose -- Images management without a specific UI for the frontend (although, slideshows are coming soon to ImageGallery). Anyway, give ImageDataObjectManager a try.

As far as docs, every day, I say, this is the day I'll write the documentation... but it never happens. So... today!!
