How to arrange subtitles under a title in Yii2 - php

Question

I am trying to arrange some subtitles under a main tile but it is repeating the title.
<div id="downloads" class="tab-pane" role="tabpanel">
<?php
$product_id = $model->id;
$downloads_model = Printingmachinedownloads::find()->where(['productid'=>$product_id])->all();
foreach ($downloads_model as $doc) {
$doc_type = $doc['type'];
$doc_label = $doc['documentlabel'];
$doc_title = $doc['documentname'];
?>
<div class="amazingcarousel-container-1 tab_style">
<h3><?php echo $doc_type;?></h3>
<a target = '_blank' href="<?php echo Yii::$app->homeUrl?>images/printingmachine/downloads/<?php echo $doc_title; ?>">
<?php echo $doc_label ?>
</a>
</div>
<?php
}
// $doc_title = $downloads_model[0]->documentlabel;
?>
</div>
</div>
The output is:
What I need is
Brochures
abc
def
ghi
Specificationsheet
xyz
lmn
opq
Can Anyone tell me what I have to do?
Thanks in Advance

If you don't have issue with new MySQL version group by concept, you can use something like:
...
$downloads_model = Printingmachinedownloads::find()->where(['productid'=>$product_id])->groupBy(['type'])->all();
foreach($downloads_model as $doc):
<div class="amazingcarousel-container-1 tab_style">
<h3><?= type['type'] ?></h3>
$subtitles = Printingmachinedownloads::find()->where(['productid'=>$product_id, 'type' => $doc['type'] )->all();
foreach($subtitles as $subtitle):
<a target = '_blank' href="<?php echo Yii::$app->homeUrl?>images/printingmachine/downloads/<?php echo $subtitle['documentname']; ?>">
<?php echo $subtitle['documentlabel'] ?>
</a>
enforeach;
</div>
endforeach;
...
If have issue with group by you can use little non standard way, it's not best practice and effective way:
$downloads_model = Printingmachinedownloads::find()->where(['productid'=>$product_id])->orderBy(['type'=>SORT_DESC])->all();
$previous_title = ''; $iteration = 1;
foreach($downloads_model as $doc):
$subtitles = Printingmachinedownloads::find()->where(['productid'=>$product_id, 'type' => $doc['type'] )->all();
$count = count($subtitles);
$previous_title = $previous_title ?: $doc['type'];
if( $previous_title == $doc['type'] && $count == $iteration ):
<div class="amazingcarousel-container-1 tab_style">
<h3><?= $previous_title ?></h3>
foreach($subtitles as $subtitle):
<a target = '_blank' href="<?php echo Yii::$app->homeUrl?>images/printingmachine/downloads/<?php echo $subtitle['documentname']; ?>">
<?php echo $subtitle['documentlabel'] ?>
</a>
enforeach;
</div>
$previous_title = ''; $iteration = 1;
else:
$iteration++;
endif;
endforeach;
I didn't test it, but something similar should work.
But my suggestion and effective way will be you use relational tables 1 title container another related table containing sub titles.
