Hey there

Even though it is often used as a selection tool, combobox is actual a textbox with autocomplete.

The main field of textbox is "value" (the text value of the field), and that value doesn't need to be matching an entry from the model to be exist in the text input.

As a result, if you want to erase the value of the combobox, you need to bind the value="@load(vm.someStringValue)" and notify change on that value object (with the value itself being null or blank string).

If you only care about selecting a value from a list of values, with filtering: Check-out selectbox (EE): https://www.zkoss.org/wiki/ZKComponentReference/Input/Searchbox
