Click or drag a box to select features, use the Shift key to add
|
|
features to the selection, use the Ctrl key to toggle a feature's
|
|
selected status. Note that this control also has a hover option, which
|
|
is enabled in this example. This gives you a visual feedback by loading
|
|
the feature underneath the mouse pointer from the WFS, but causes a lot
|
|
of GetFeature requests to be issued.
