[MaterialTextField] Input type "Autocomplete"

[pkozak2]

Is your feature request related to a problem? Please describe. InputType Choice is OK, but why not have autocomplete combobox? There are some controls, but not in XF-Material design.

Describe the solution you'd like I can provide static items for user and update from background (when TextChanged event), so will be nice to have Loading text. Choices will be shown below Textfield, and I can select one from list or complete text from keyboard. Suggestions can be object, eg. {Id, Value}.
