[select* position-job class:form-control id:position-job first_as_label “—select—” “Cloud Architect” “Storage Administrator” “Storage Architecture” “Mainframe Specialist” “Cognos Specialist” “.Net Developer” “Mobility Platform Expert” “Backup Administrator” “Backup Solution Architect” “Network Administrator” “Network Architect” “Cyber Security Specialist” “IoT Specialist” “Security Specialist”]

<select class=”form-control validate[custom[dropdown]]” id=”position_job” name=”position_job”>
<option value=” – – – – – – Select – – – – – “> – </option>
<option value=”1″ <?php echo(isset($_POST[‘position-value’])&&($_POST[‘position-value’]==’1′)?’ selected=”selected”‘:”);?>>Cloud Architect</option>
