As per the standard there is no close button for combo-box, it's part of UX I guess.
May we can make it hide with props if they don't want or by default it will be hidden and can have it with props

@prasanna1211 and @sandeepprabhakaran Do we need close button on the listbox?
In my opinion, we can have it, or make it as prop to show or hide.

With props, yes I think.
