[OpenLayers-Users] turn features on and off

[Arnd Wippermann]

A lightweight solution of your idea are possible without a patch. 

With a feature attribute i.e 'group' for the features of a vector layer,
it's possible to change the visibility of features with using
addUniqueValuesRules.

Example :

group.html

Hi,

>I'd like to turn off a group of animals (a group of points declared by 
>there attribute). It's not enough to turn them off by opacity because

you could try the grouping-vector-features.patch. Find details on the
project page http://ol.m-click.ws/

example - http://ol.m-click.ws/demo.html patch -
http://ol.m-click.ws/grouping-vector-features.patch

Regards, matt
