Today we use the idea portals in different contexts, and several cases we have rather long forms with different sections. It would be beneficial to be able to format the form a bit more into sections / enable a line to divide different parts of the form. Even set different background colors for the different parts would be great. Alternatively add the possibility to format the text & boxes on individual parts.
This is possible today using dynamic forms with Ideas Advanced. You can break your idea submission forms into steps with conditional rules to streamline the way you capture ideas. See how it works.
