Remove menus
Since the biggest problem with the current navigation is that there are many types of menus with different looks, function and location, the most important thing in the proposed solution is to reduce the number of menus. The solution is therefore to remove all menus that are not included in the proposal for new menus.
When they are removed, you can consider whether to replace them with one of the menus in this proposal or whether it is possible to take the opportunity to remove information or put it in a more logical location.
Consistent appearance and placement of components
When menus are removed and this proposal is implemented, it becomes a much more consistent appearance and placement of menu components. Complete this by doing the same with other components.
Fix responsive design
When the new menus are implemented, responsive design will work better than with current menus. In addition to implementing these correctly, the rest of the site needs to be reviewed and fixed so that it looks good in all screen sizes. Above all, it must never be the case that things can end up off the screen.
Colors
The new navigation uses a new color palette. The old colors are too strong and does not work well together. Therefore, the rest of the site should also be changed according to these colors in a later stage.
