To build an expanding creative,which three panels must be included in the HTML?(select three)

To build an expanding creative,three panels that must be included in the HTML are Collapsed,Expanded,andMain. The Collapsed panel is necessary because it represents the initial state of the creative when it's minimized or not fully expanded. The Expanded panel is crucial as it displays the fully opened or expanded state of the creative,showing the complete content or functionality intended for the user.The Main panel,though not explicitly highlighted as a correct answer,is typically essential because it encompasses the core content or functionality that is visible or accessible within the creative.Together,these panels allow for the dynamic interaction where users can toggle between different states of content visibility or functionality,enhancing user experience by providing options for both minimized and expanded views.
