📖 Description

This PR introduces the ability to close the dropdown of a FluentAutoComplete in code. There could be others but my use-case is that I have a button in the 'Footer' of the dropdown that allows a user to open up a more advanced dialog for searching for a result (shows a grid). When this button is pressed, a dialog is opened but because the dropdown of the autocomplete is still open, it displays over the dialog. Here is a screen capture of that happening:

📑 Test Plan

Run the demo project and go to the Autocomplete page. Then go to the Close via code section, invoke the dropdown and then click on the button in the footer.

Here is an example of it working:
