Add Prop to prevent delelecting option in Listbox

[katerlouis]

Currently, when you click on the currently selected Item in Listbox, the item gets deselected and the modeled value is set to null. It would be great to have an option to prevent that.

Any update about this? It would be great indeed to have a mandatory prop to avoid setting the model to null.

By the meantime, I have published a package with a Vue directive for getting a similar behaviour. The package with instructions can be found here.

Greetings!

Is there any plan on implementing this behavior?
