I'm creating a wizard prototype in which a user needs to fill in a document through certain steps. There are 2 functionalities i have difficulty with:
In one of those steps the user needs to create goods and containers and then link them together. Linking them requires quite a lot of functionality and two tables (goods and containers) lined out next to each other for drag and drop. This linking screen should ideally be on its own because i need all the real estate i can get. Logically i'm thinking of a popup screen within the wizard which he accesses by clicking a 'link' button in the goods/container wizard step. However i don't feel good about using a popup within a wizard. I'm unsure if this is good practice.
In another step in the wizard, the user can access a budget page. This also should be presented in a separate popup but the thing here is that the budget page is also accessible from outside the wizard (unlike the linking page). Can the user (who is inside the wizard) be taken to a page that normally lies outside the wizard? What happens when the user clicks the 'save' button in the budget page? He gets taken back to the wizard? Soemhow this doesn't feel right.
Thank you for replies.
