How do I hide a metafield when it’s blank?

[bovinaceae]

I have a clothing store and I want to hide ‘size chart’ field on certain product page. I’m using Dawn theme.

If it is a predefined block that uses a metafield definitions as a dynamic source then you will want to create an alternate template to use on the products that have no style guide.

If you are using a a custom-liquid block|section simply use a liquid if tag to conditionally check if the metafield exists {% if product.metafields.information.size_guide %}.

Or is blank {% if product.metafields.information.size_guide != blank %}.

Yes that worked. Thanks for your help!

Here is the best way I used to solve this problem:

Step 1: Add "Custom liquid/Custom HTML" block instead of Text block.

Step 2: Go to Dashboard -> Settings -> Custom data -> Products

Step 3: See all the keys generated to access your metafields example: "product.metafields.custom.gemstone_size"

Step 4: Go to Dashboard -> Customize

Step 5: Go to product or any other page where you are displaying metafields (in my case I need on product page)

Step 6: For individual metafields to display, just add "Custom liquid" block and put the conditions like this:

{%- if product.metafields.custom.gemstone_size != blank -%}
<strong>Gemstone size (cm):</strong> {{ product.metafields.custom.gemstone_size }}
{%- endif -%}

In your case the keys for displaying metafields will be different. For each metafield to display you need as many "Custom liquid" blocks and need to put conditions accordingly.

Hope! I answered the question.
