[OpenLayers-Users] Sort of Feature switcher

[Arnd Wippermann]

Hi Pascal,

Interesting problem. I have added some functionality to the last example.
Perhaps it helps.

I use a stylemap with addUniqueValueRules for the gml layer with a rule for
attribute visibility.
If the attribute visibility = "visible" the feature is visible.
To change the visibility, I change the attribute of the feature to "hidden"
and redraw the feature.

I'm not sure, if it's the straight way, to change the visibility of
features.

Betreff: [OpenLayers-Users] Sort of Feature switcher


Hello,

Thanks to Arnd, I have implemented a GML layer with some polygons on top of
an other layer (now WMS). Some polygons are one over an other and sometimes,
it is simply not possible to select one polygon as it is behind some others.
For this reason and also to ease the User Experience, I would like to have a
sort of Feature Switcher:
Like the current layer switcher but instead of just viewing/uviewing the
different layer, I would like also to view/unview each feature of my GML
file.
So the user would be able to view only some specific polygon features.

Is there some way to do this?
thanks
