How in Yii 2 to immediately display a double set of data from one table without duplicating the code, one full, the other partial?
Example https://yadi.sk/i/Luz7-WfZ3LkrPY
On the left there are only 10 records (filtered by some attribute), on the right on the map all records from the table

Answer 1

give an example of a working code with duplication, and we will tell you what to fix.
ps. My option is to leave it as it is and continue to work on the rest of the functionality and start earning $ as soon as possible

Answer 2

How to immediately display a double set of data from one table in Yii 2 without duplicating the code

What's the problem?

$data = Mymodel::find()->all(); //все записи
$data10 = array_slice($data, 10); //первые 10 из всех записей

If you have already received everything, then you already have 10. More to think about:

$data = Mymodel::find()->all(); //все записи

//выводим первые 10
for($i=0;$<10;$i++){
echo  $data[$i]->title;
}

//выводим все
foreach($data as $one){
echo  $one->title;
}
