In case of a triplet of select province / city / postal code, you cannot manage the disabled status, you can only initialise it disabled or not. The same goes for updating the url, as when changing province I have to reload cities updating the url and empty&disable the postal code select.
I have seen that by updating the select options manually they are also reflected in the component, but this does not happen for the disabled state.

- the height property doesn't seem to work, the dropdown will be long based on the number of options.
- allowClear doesn't seem to work
