When LocalVolume CR is getting created from the form view of OCP webconsole the nodeSelector section is not getting shown and not able to configure it with form view. 
It is important to have nodeSelector section in LocalVolume CR since by default it will try to select the disks on all possible worker nodes which is not valid case. 
Also, in Yaml view the sample yaml doesn't show the nodeSelector condition as mentioned in examples of LocalVolume documentation:

Node selector section is not shown.

Node selector option should be there in form view as well as in yaml view of LocalVolume creation steps with OCP webconsole.
