Hi TurricanDE,

Unfortunately, I was not able to reproduce your issue. This is an example of an Editable ListBox:
<div><ListBox Editable></div>
<div>    <ListItem Label=”Item 1″></ListItem></div>
<div>    <ListItem Label=”Item 2″></ListItem></div>
<div>    <ListItem Label=”Item 3″></ListItem></div>
If the demo above doesn’t work for you, please provide us with a sample code of your page and the version of your internet browser.

If you have any other questions, please do not hesitate to contact us again.
Best regards,
