Hi guys,

In my use case, I have a Form with 2 EuiComboBox. Both combo boxes can't have the same fields, but have the same options. So when i change one combo box, the options can't show anymore the selected value previously.  
For example:

```
let options = [{"label": "a"}, {"label": "b"}, "{label": "c"}, {"label": "d"}];
let comboBox_1_fields = [];
let comboBox_2_fields = [];

```

In combo box 1 I choose `label "a"`, so:

```
possibleOptions = [{"label": "b"}, "{label": "c"}, {"label": "d"}];
comboBox_1_fields = [{"label": "a"}];
let comboBox_2_fields = [];

```

Then I choose `label b` in combo box 2:

```
possibleOptions = ["{label": "c"}, {"label": "d"}];
comboBox_1_fields = [{"label": "a"}];
let comboBox_2_fields = [{"label": "b"}];

```

Finally, i remove `label a` from combo box 1:

```
possibleOptions = [{"label": "a"}, "{label": "c"}, {"label": "d"}];
comboBox_1_fields = [];
let comboBox_2_fields = [{"label": "b"}];

```

Can anyone help me with this?

Hi @koyassan  
I'm not sure I understand correctly your question, but seems a bit more a React/JS question than a Kibana one.  
The EuiComboBox works like every other React component, so if keep track of the change using the `onChange` props you can also update the state of parent component removing the selected option from the `possibleOptions` array and re-rendering the form with the updated possible options array
