Tuning the "List" view

[mjesteve]

When the component is used as if it were a "List", initializing the option keepAlwaysOpen to True, some behaviors are missing that are not necessary when we use it as a "ComboBox", for example:

• The need for the dropdown to automatically adjust to the parent container of the component and consequently change the number of options to be displayed in it automatically. In these cases the "OptionsCount" property must be recalculated each time the container is resized.
• Or the need to make visible "always" the option that we have selected (scrollToIndex) because when the value is changed, through code, the desirable thing is that the option that we have just set can be seen.

Let me know your opinion about these new features please.
