In line with the example for dependent selects (which gives an error at my browser, but I tried it with my local server and then it works), I was wondering if is possible to (and if so, how):
- Select a default first item when the category changes. Thus defaultToFirstOption = true in the second box (item).
- Prevent a fetch for the second box (item) as long as no category is selected. Disabling the combobox is also an option.
