4,complaint type 4
5,complaint type 5
6,complaint type 6
7,complaint type 7

PHP code

<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()}" onchange="selectAnswer(this)">
   <option class="hidden" disabled="disabled" value=""></option>

<?php

$file_handle = fopen("../complaint.csv", "r");

while (!feof($file_handle)) {

$lines_of_text[] = fgetcsv($file_handle, 1024);

}
fclose($file_handle);

foreach ( $lines_of_text as $line_of_text): ?>
        <option value="<?php print $line_of_text[0]; ?>"><?php print $line_of_text[1]; ?></option>

Question:

If a Main complaint item is select then that same complaint does not appear in Additional Complaint list (i.e. if 'complaint type 1' is selected for Main complaint, 'complaint type 1' does not display on Additional Complaint list)

How should I get that using one complaint.csv file like 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?

Can anyone please suggest any solution?
