How to support application users who perform only a single operation
A developer asks: For a restricted-security subgroup of users who are only allowed to perform simple queries, how can I display the portal with no left panel, or the left panel collapsed (closed) and the expand/collapse control disabled?
A reasonable approach to your requirement is not to display the portal at all.
You can specify a custom activity in the Operator ID instances of the restricted-security operators. For example, you can reference an activity that, instead of displaying a portal, presents a simple HTML query form allowing them to enter query parameters, submit the form, and review results.
Don't forget to provide these users with a way to log off.
