Combo box issue.

Summary:

Hello,

Please, I would like your help with the following.

I have a simple combo described bellow, for YES/NO values.

The issue is that the user can type anything in the field.

Does the combo works this way? or can I do something to limit the values to YES/NO.

It seems not very clean that the user can type on the field.

It should only allow to select the values provided in the combo.

Thanks

Juan
