Answer 1

Use these properties

$('#placeSelect').select2({
width: '100%',
allowClear: true,
multiple: true,
maximumSelectionSize: 1,   
});

just call this function on onchange event of dropdown

function ResentForMe(){
var _text=$('.select2-selection__rendered li:first-child').attr('title');
$('.select2-selection__rendered li:first-child').remove();
$('.select2-search__field').val(_text);
$('.select2-search__field').css('width','100%');
}

Note: Remove "Multiple" attribute from select
