In erase command. I realise, when i select a set of objects. It not highlighted. Instead it fade the selected objects i choose. How can i make a select prompt like that?

There could be different ways to do it. But simplest way would be using HighlightOverrule. Here is a post I wrote almost 15 years ago that show how to do similar as you described (I just changed the color of the highlighted entity. Obviously, you can also change the entity's Transparency as well):
