It works OK if you use :clear-icon-cb="()=>selectedID=null" but in console you say is deprecated

I completly agree with @arcreative.

“null” is a proper state. Undefined is not. In JavaScript, undefined will essentially remove the referenced property. I’d argue that undefined is not the correct state for the vast majority of use cases.

There’s no reason not to allow null values to be selected and also allow “clear” to default to null, but have the edge case where people want a clearable select list for a list containing a null to be forced to use the $nextTick(()=>object.value=undefined) hack to set to undefined.

I will strongly argue that setting a value to null on clear is NOT an edge case.

Any updates on this? Would be really awesome for it to be set to null rather than undefined.
