Delivery Time should be dropdown

General

• Magento version: 2.1.6
• PHP version: 7.0.18

Issue description

Delivery time is set by default to "2-3 Tage". If you have a german and english store view, you will have to create a store view product version to override this. That is not practical. Making the delivery time attribute a dropdown with default "2-3" would solve this issue.

If it is a dropdown, you also have to manage translations for all possible delivery times as well.

But there does not seem to be a better solution, as we might also write "1 Woche" or so -- so making it a dropdown is probably the most practical solution.

@johnny-longneck want to make a pull request?

or shall we?

@maintainers: do you see a change this would be merged?

Workaround:

• In eav_attribute set backend type = int; frontend input = select

• Include on catalog_product_view / catalog_category_view:

    <referenceBlock name="product.info.delivery">
        <arguments>
            <argument name="at_type" xsi:type="string">text</argument>
        </arguments>
    </referenceBlock>
