Pre-order in a Clean Themes Sectioned theme (excluding Boost)

instructions.txt

Warning: This does NOT work with quick-buys.

1. Copy and paste the following to the bottom of Templates/product.liquid:

{% for collection in product.collections %}
{% if collection.handle == 'pre-order' %}
  <script>$('[action^="/cart/add"] input[type=submit]').val('Pre order'); theme.OptionManager.strings.buttonDefault = 'Pre order';</script>
{% endif %}
{% endif %}


2. Create a new collection called "Pre order", and add any pre-order products to it.

Done.
