You just lack the lflag in dom. lfor "length changing input control".
你只是缺少l的标志dom。l用于“长度改变输入控制”。
dom: 'lBfrtip'
will make the dropdown to reappear.
将使下拉菜单重新出现。

I know it is too long, but if some one still facing this issue, then please do the following, it is an alternate answer.
我知道它太长了，但是如果有人仍然面临这个问题，那么请执行以下操作，这是一个替代答案。
Add 'pageLength' inside buttons as follows:
在按钮内添加“pageLength”，如下所示：
$('#example').DataTable( {
dom: 'Bfrtip',
buttons: [
'pageLength','copy', 'csv', 'excel', 'print'
]
} );

This works for me:
这对我有用：
$(document).ready(function(){
dataTable = $('#myDataTable').DataTable({
"processing":true,
"serverSide":true,
dom:'lBfrtip',
buttons: ['excel', 'csv', 'pdf', 'copy'],
"lengthMenu": [50,100,500,1000,2000,5000,10000,50000,100000],
"order":[],
"sScrollX": "100%",
"scrollCollapse": true,
"ajax":{
url:"FetchAllAjax.php",
type:"POST"
}
});
});
