Masking

A Mask uses conditions to hide or display answer options in a question based on a participant's responses or profile data.

Example: Use a profile variable to hide answers
You want to ask participants where they have shopped for groceries in the last three months; however, you want to hide the stores that participants cannot shop at in the province where they live. In the following example, participants who live in British Columbia cannot shop at `IGA Extra` and `Sobeys`. When you create a mask based on a profile variable, participants who live in British Columbia will not see `IGA Extra` and `Sobeys` among the answer options. For information on how to create this example, see Masking examples.

Example: Use a mask to show answers in a question
You want to ask participants the make and model of the car they own. The list of car models can become quite extensive, therefore, you would create a masking condition to only show cars based on the brand of car the participant owns. For the first question the participant selects `Toyota`. In the second question, the participant will only see cars made by Toyota. For information on how to create this example, see Masking examples.
