Hi and welcome
You can use QCompleter
http://doc.qt.io/qt-5/qtwidgets-tools-completer-example.html
here it uses files but list can be anything.

@mrjj is there a way to use QCompleter in form design

[mrjj]

@davidlabib
nope as its not visual.
But you can assign it to Edit you have placed on form. (UI)
so almost yes.
All it takes is

(after setupUI())

QStringList wordList;
wordList << "alpha" << "omega" << "omicron" << "zeta";
QCompleter *completer = new QCompleter(wordList, this);
completer->setCaseSensitivity(Qt::CaseInsensitive);
ui->lineEdit->setCompleter(completer);
