I want an auto-suggest feature in my Combo Box. Here's what I want to happen:
1. I want the suggestion to appear like Visual Studio's intellisense wherein if I type a command, it suggests the possible ones based on the letters I typed and bolds them
2. It needs to be a combo box and NOT a text box because I don't want users entering invalid items inside the text box
3. If the combo box suggestion closes with a text that's not in the result, the text clears but if there's at least one result, it automatically chooses that.
