Hi Venu,
When you click on the properties of a widget or container there will be a section called “visibility”. Here you can set the visibility of your selection based on a module role, attribute value of the entity that is the data source of the dataview that its contained in, or using an expression. The expression gives you more flexibility to show or hide your selection based on the multiple conditions. For example you could write something like this :
if attribute 1 and attribute 2 were questions on your form you could write
$CurrentObject/attribute1 != empty and $CurrentObject/attribute2 != empty
This will make your selection appear only after the the first two questions are answered.
Another option would be to hide the data using entity access rules. Here is some helpful documentation for that.

Hope this helps!
