Here is the sample data in the array. $product.features.name: $product.features.value

width: 100 m
method: Nail Down

Here is the smarty code i have

{foreach from=$product.features item=feature}
    <div class="col-md-3 col-sm-6 col-xs-12">
        <div class="name">{$feature.name}</div>
    </div>
    <div class="col-md-3 col-sm-6 col-xs-12">
        <div class="value flex_child">{$feature.value}</div>
    </div>         
 {/foreach}

Answer 1

Try this:

{foreach from=$product.features item=feature}
    <div class="col-xs-12">
        <div class="name">{$feature.name}: {$feature.value}</div>
    </div>         
{/foreach}

Answer 2

One option is to prepare the features array for looping the keys and values.

For example, using array_reduce and explode to return an array where the keys are the part before the : and the values are the imploded result with , as the delimiter:

$features = [
    "width with: 100 m",
    "method: Nail Down",
    "method: Main Floor",
    "Warranty: 25 years",
    "Color: Red",
    "Color: Blue"
];

$features = array_reduce($features, function($carry, $item){
    $parts = explode(":", $item);
    $carry[$parts[0]][] = $parts[1];
    return $carry;
});

foreach ($features as $key => $value) {
    echo "$key: " . implode(',', $value) . PHP_EOL;
}

Output

width:  100 m
method:  Nail Down, Main Floor
Warranty:  25 years
Color:  Red, Blue
