Autocomplete input class

[NeoCoderMatrix86]

Hello,
I would like to use the Autocomplete component inside a project. Since currently the user input is a TextEdit, the replacement by Autocomplete seems pretty simple, but now I'm facing a problem: I change the TextEdit class if the user input is empty to "alert-warning". Since the Autocomplete component is rendered as div, with a input below, the class changes are applied to the div and not to the input. Is there a possibility to define the TextEdit as Renderfragment?
