UI bug fix - Githubissues

Value proposition

As a user of the DIY App I want to filter or sort the projects, I also want to search for specific words In order to find specific projects.

the user can sort, filter or search for specific projects via a static search menu
the search menu is under the Header on the overview and favourites page
to sort the user chooses one of the options shown in the drop down menu that appears after clicking sort
to filter the user chooses one or more of the options shown in the drop down menu that appears after clicking filter
the user can see what is sorted or filtered or searched in this search menu

[x] create feature branch feature/UI-bug-fix
[x] add a static section under the Header, above the overview, that contains sort-, filter-, search- function
[x] move the sort-, filter-, search- function from the component Navigation to the new section
[x] change radio buttons of sort- and filter- function to drop-down to display of what is sorted or filtered
[x] moves to next US(Design) to minimize work: style the search section according to App design
[x] fix bug: filtering projects on the Homepage lead to filtered favorite, instead of ALL favorites (can lead to empty fav- even though it may not be empty)
