How to make cart note a mandatory field in Mr Parker 2.0 theme?

Technical Q&A

Topic summary

Goal: Make the cart note a mandatory field before checkout in the Mr Parker 2.0 theme.

  • Proposed approach: In most Shopify 2.0 themes, the cart note is a textarea with name=note, located in cart-footer.liquid or near the cart subtotals. Add the HTML required attribute to that textarea to enforce browser validation.
  • Evidence: A helper referenced an example textarea with the required attribute (exact code not shown in the thread).
  • Related attempt: Another user on the Dawn theme found a textarea with class text-area field__input and said they added required, but it did not work.
  • Next step: The helper asked for the exact code from the non-working case to diagnose placement/markup.

Status: No confirmed solution yet; discussion is ongoing and awaiting a code sample for troubleshooting.

I am hoping to do the same thing and using Dawn. I found where you have this code and mine just had class="text-area field__input and I just added required but it didn’t seem to work
