I want to design a panel in the below mentioned way.
It will take four inputs. username, place, feature1, feature2.
When the place is US, all the features can be accessile.
When the place is other than US, the feature1 should not be accessed.
That is the user should not be able to enter any value in the panel for that feature.
Whether this type of locking an input variable can be done in panels. If so, please let me know how to do that.
