It refreshes the page which takes a little while and mainly the page jumps back to the top - in case that when adding many items this might get quite anyoing. Please suggest me solution.

The simplest solution is snippets

$multiplier->addRemoveButton('Remove', function (Nette\Forms\Controls\SubmitButton $button) {
    $button->setHtmlAttribute('class', 'ajax');
    $button->onClick[] = function () {
        $this->redrawControl('mySnippet');
    };
});
$multiplier->addCreateButton('Create', 1, function (Submitter $button) {
    $button->setHtmlAttribute('class', 'ajax');
    $button->onClick[] = function () {
        $this->redrawControl('mySnippet');
    };
});
