Cascading DropDown
I'm using MVC (.NET5) with EF and had this code to select a species on a View (to Create/Edit):
It displayed every species but I wanted to have another drop down list that displays the taxonomy or class of a species, for example Mammal, and then filters what the species drop down displays. For example if Mammal is selected (id/index == 1, for example) in the taxonomy list, then the species list will only display the options that have that matching foreign key.
After spending pretty much all day trying to find a good explanation I'm a bit defeated. I was trying to follow https://stackoverflow.com/questions/46954959/how-to-create-cascading-drop-down-list , but unfortunately it doesn't seem to convey a deep enough explanation to me.

I have on the PetViewModel class:
