can you elaborate on your problem? when you have set the allowempty prop, the selectinput should be empty by default. i was able to reproduce the desired behavior with the follwing code:
<selectinput
source="test"
label="test"
allowempty
choices={[
{ id: "1", name: "yo" },
{ id: "2", name: "yoyo" }
]}
initialvalue="" // this line can be omitted
/>
one problem i could think of would be when you have set default values for the <form />
component you're using, <simpleform />
per default.
