is there any way to add button into dropdown list with textfields using controlfx jar - javafx

Question

i have a textfield with autocomplete and i want to show button near each item appeared into that list
this is my code
List<String> s = ms.getUsernames(ms.getUser(7).getListamis());
TextFields.bindAutoCompletion(txtsearch, s);
this is the method getusernames
public List<String> getUsernames(String list_amis) {
List<String> ls = new ArrayList<>();
String [] idmember = list_amis.split("/");
for (String i : idmember) {
ls.add(getUser(Integer.parseInt(i)).getUsername());
}
return ls;
}
this is my output
i want to add a button near testing as a result i can get its ID

Answer 1

This is the solution I came up with. There certainly is a better way that is more elegant and works better, but I guess this would work for many situations. You would have to do something about the size of the ListView, though, and I didn't test this in an environment in which the appearing ListView might change something about the design of the rest of the UI. I suggest putting the whole thing into a PopOver or something.
