i have a optional TreeDropdownField. how can i remove the link after setting?
If this is SS3 you can call the create the field using teh ORM pattern as opposed to the old new TreeDropdownFIeld and then just chain on setEmptyString
so instead of something like
$fields->addFieldToTab("Root.Main", new TreeDropdownField("RelationID","Title","SiteTree"));
you could do
$fields->addFieldToTab("Root.Main", TreeDropdownField::create("RelationID","Title","SiteTree")->setEmptyString('(Select page)'));
Hi. I'm looking also for an solution for that issue.
Your solution won't work because TreeDropdownField has no method setEmptyString() because its not a child of DropdownField.
In the forum I came across something like this http://www.silverstripe.org/form-questions/show/5733?start=16, but this wraps the whole tree inside the reset link. Works, but is not very nice.
Isn't there any easy solution? I wonder that this isn't build in by default :-(
