Value suggest feature in Advanced search

Hi everyone,
First post from me here. I’m working from the Netherlands on the collections of Tresoar, Frisian Heritage.
There is one relatively straightforward issue I keep comin across and that is that when i’m using advanced search, I always have a hassle with getting the correct element from the correct vocab. This is because I cannot choose the identical/equivalents between the vocabs that I have in my application like when you are editing a Resource Template. It would be very helpful for me to get the dropdown menu with the options listed from the vocabs that I have available so that I can choose the right ‘creator’ element in one go, to conduct my search.
Thanks in advance!
Best, Reem
