As you can see from my video (is there also a small demo source inside zip) https://www.dropbox....mbobox.zip?dl=0
The official delphi TComboBox component support keyboard also with style set as csDropDownList!
If the user press key faster can easily select an item. Thi is very important if you have a combobox with many items.
In alternative in fact select a item is very difficult because you must search it with scroll bar.
Your TNxComboBox and also a component TNxComboBox based like TNxComboBoxColumn and others don't support this features.
Many times I have ask you buy forum and email to add this features.
So please can you add it on v5 and v6 version of your components?
I think you can see the code of officail TComboBox to have an idea about it.
Please this is a very important feature.
What do you think about it?
