So many buttons in the consumable edit form

[lache-melvin]

Expected Behaviour

I think it would be more pleasant to input consumable data if there was only one button at each level 😅 This might also make it more obvious that certain levels are in fact optional?

Current Behaviour

Because each layer in the consumable tree is optional, we're getting a lot of buttons in the form...

Possible Solution

Merge the buttons at each level into a split button, so the user can add the field they want to add, and the screen isn't filled with so many buttons
