显示复选框项目列表（选定的下拉项目除外）

我有一个下拉列表项和一个弹出框（用于打开弹出框的颜色框）和一个复选框列表。单击“ +添加/编辑”显示弹出窗口。下拉菜单项和复选框都是通过PHP从complaint.csv文件中生成的。

投诉.csv文件

1,complaint type 1
2,complaint type 2
3,complaint type 3
etc...

PHP代码

<label class="question-name" ng-class="{error:hasError()}">
  <span class="ng-binding" ng-hide="question.nameHiddenOnMobile">
    Chief Complaint
  </span>
  <span class="icon-required" ng-show="question.required"></span>
</label>

<select name="Language.PrimarySpoken" ng-hide="showAddAnswer"
        ng-model="question.response.value" 
        ng-options="a.text as a.getText() for a in question.answers.items"
        id="Language.PrimarySpoken" ng-value="a.text" class="input-wide" 
        ng-class="{error:hasError()}">
  <option class="hidden" disabled="disabled" value=""></option>

    $file_handle = fopen("../complaint.csv", "r");
    while (!feof($file_handle)) {

    }
    fclose($file_handle);

    foreach ( $lines_of_text as $line_of_text):

题：

1. 如果选择了主要投诉项，则该投诉不会出现在“其他投诉”列表中（即，如果将“主要投诉”选择为“投诉类型1”，则“投诉类型1”不会显示在“其他投诉”列表中）

How should I get that using one complaint.csv file like checking for the selected item, and avoid it when displaying the list e.g on select 'complaint type 1', the data from complaint.csv file will be display on popup checkbox list except 'complaint type 1' which is selected?

2. There is empty space generating if we remove the element. I don't want the empty space of removed item in checkbox list. Empty space means if 'complaint type 2' is removed then there empty space creates between 'complaint type 1' and 'complaint type 3'.

Is there any way to have AJAX for this situation like when the item is selected AJAX will call and it will remove the item from the checkbox list which is selected and then load the new items list except the selected one. (right now both list are loading at a same time on page load insted of that using AJAX the dropdown list should load on page load and checkbox list on click '+Add/Edit' button avoiding selected item.) Thus might be the empty space will not be there.

How this should be done using AJAX?

OR

Can anyone please suggest any solution with PHP or JS to get both requirements?
