Add example to docs for Combobox that uses value property

[glennpierce]

Combobox has a property and i can't find and example of using it.

value Model

The examples all use selected_options even when the first couple of examples are single strings should they not use value ?

What is the difference between value and selected_options ?

I am trying to fix a bug where updating selected_options does not change the dropdown and thinking it would be easier with value.

Thanks

What is the difference between value and selected_options ?

• The value attribute is the value displayed in the input box, usually the text attribute of the selected ComboboxOption component.
• selected_options is the value attribute of the selected ComboboxOption component.

I am trying to fix a bug where updating selected_options does not change the dropdown and thinking it would be easier with value.

The reason why the selected_options is updated without changing the drop-down menu is to match the behavior of Fluent.

So if I understand correctly, if I need the force the combobox to change in code I could fake it by setting value ? or would that show a mismatch when opening the dropdown. What would be your suggestion for this case ?

My current suggestion is to set the value of value when you update the selected_options value.

However, in the next version (V5), maybe we should consider automatically setting the value of value when the user updates the selected_options value.
