Yii2: Adding dynamic DateControl fields from related model to a form - datepicker

Question

I have three models: User, Job and UserJob. The models User and Job have n:m relation. In the user form I need to dynamically add new jobs.
In the model User I get the jobs related to the current user:
public function getUserJobs() {
return UserJob::find()
->where(['user_id' => $this->id])
->orderBy('start DESC')
->all();
}
In the views/user/_form.php are the existing jobs added to the form as follows:
if (isset($userJobs)) {
$i = 0;
foreach ($userJobs as $job) {
$i++;
...
echo $form->field($job, '['.$i.']start')->widget(DateControl::className(), [
'type' => kartik\datecontrol\DateControl::FORMAT_DATE,
'saveOptions' => [
'name' => 'job_start[]',
],
])->label(false);
...
I add new jobs with jQuery (similarly as in these examples). For most fields it works perfectly. But there is a problem with the field start, which uses the DateControl extension. The extension produces its own jQuery script. Without manipulating this script the start field can not work correctly.
Is there a way how to dynamically add new DateControl fields to the form?

Answer 1

A possible solution is to add a few hidden rows with job-fields:
for ($j=$i; $j < $i+3; $j++) {
$job = new MitarbeiterJob();
echo '<tr style="display:none;" class="new_job">';
...
echo $form->field($job, '['.$j.']start')->widget(DateControl::className(), [
'type' => DateControl::FORMAT_DATE,
'saveOptions' => [
'name' => 'job_start[]',
],
])->label(false);
}
...
If a user clicks on the button 'Add a new job', then a jQuery script shows one of the rows.
It works, but the solution is not optimal...
