The displayValue should work with nested values (e.g., drop-down values located within a dynamic matrix or panel) #7876

T16865 - Using dynamic panel values in HTML markup https://surveyjs.answerdesk.io/internal/ticket/details/T16865

The displayValue function accepts the name of a question. However, when a drop-down question is located within a dynamic panel, it doesn't work. Similarly, it doesn't work for drop-down cells within a dynamic matrix.

displayValue('panel.activityCategories[0].activityCategory')

Another question: T16867 - Totals calculation https://surveyjs.answerdesk.io/internal/ticket/details/T16867

I created a separate Expression column to work around this: "sumInArray({question1}, 'Column 4')". Because the sumInArray didn't work if I pass the displayValue('Column 1').

@andrewtelnov it would be nice to have the displayValue function work out of the box in these scenarios.

@JaneSjs In general case, it is better to handle survey.onGetQuestionDisplayValue event. In the customer case, since they are using component, they can override getDisplayValue component handler.

Thank you, Andrew
