How to disable a tree node in checkbox theme

[Lucy]

Hi there,
Has any body ever tried to disable a tree node (or make it invisible)
in checkbox theme?
I need to do this to prevent users from reselecting the same node
after they tick and save to a short list.
Thanks
Lucy

Use the latest commit (as it has some bugs fixed and you can lose the
UI plugin too) and then use the types plugin and:

1) Either give your disabled nodes a type and set it to:
"disabled" : {
"check_node" : false,
"uncheck_node" : false
}
// Your disabled nodes should have their "rel" attributes set to
"disabled"
// You can change that name and the attribute if you will - read the
types plugin docs

2) Or use the default type:
"default" : {
"check_node" : function () {
if(node_should_be_disabled) return false;
return true;
},
"uncheck_node" : function () {
if(node_should_be_disabled) return false;
return true;
}
}

I hope this helps :)

Cheers,
Ivan

Hi! Is there a similar way for version 3?

[Ivan Bozhanov]

There is the `enable_node` and `disable_node` functions, or you can use CSS to hide the checkbox if that is what you need, but disable_node will probably what you need.

Best regards,

Does the disable_node and enable_node work with types?

[Ivan Bozhanov]

I am not sure I get the question - there is no conflict between the two. However you can not set any state properties (opened, selected, disabled) form the type, the types plugin is not used for this.
