Add Caption field to Multicolumn section - Dawn theme

Topic summary

A user is attempting to add a caption field to the multicolumn section in Shopify’s Dawn theme, similar to the existing caption functionality in the multirow section.

Current Status:

  • The user has partially implemented the caption feature by modifying the multicolumn liquid file
  • Screenshots show the multirow setup (working reference) and the multicolumn attempt (not functioning correctly)
  • Something appears incorrect with the implementation

Code Changes Made:

  • Added caption check to the empty column conditional logic
  • Included caption rendering block with {{ block.settings.caption }}
  • Added caption field definition in the schema with type “text”, id “caption”, and default value “Caption”

Issue:
The implementation is incomplete or malfunctioning—the user notes “something is not quite right” with their code. The full liquid code provided appears truncated or corrupted at the end, suggesting potential syntax or formatting issues that may be preventing the caption field from displaying properly in the theme customizer.

Hello, I would like to add a caption field to the multicolumn section customizer similar to the multirow section for the Dawn theme.

Here is the Row set up:

I somewhat have the multicolumn set up for a caption but something is not quite right below with the code I added as you can see below

I only added the following sections to the multicolumn liquid:

{%- for block in section.blocks -%}
          {%- assign empty_column = '' -%}
          {%- if block.settings.image == blank
            and block.settings.caption == blank --only added this
            and block.settings.title == blank
            and block.settings.text == blank
            and block.settings.link_label == blank
          -%}

{%- if block.settings.caption != blank -%}
                  

                  {{ block.settings.caption}}

                {%- endif -%}

{
          "type": "text",
          "id": "caption",
          "default": "Caption",
          "label": "t:sections.multicolumn.blocks.column.settings.caption.label"
        },

Here is the full liquid:

{{ 'section-multicolumn.css' | asset_url | stylesheet_tag }}
{{ 'component-slider.css' | asset_url | stylesheet_tag }}

{%- style -%}
  .section-{{ section.id }}-padding {
    padding-top: {{ section.settings.padding_top | times: 0.75 | round: 0 }}px;
    padding-bottom: {{ section.settings.padding_bottom | times: 0.75 | round: 0 }}px;
  }

  @media screen and (min-width: 750px) {
    .section-{{ section.id }}-padding {
      padding-top: {{ section.settings.padding_top }}px;
      padding-bottom: {{ section.settings.padding_bottom }}px;
    }
  }
{%- endstyle -%}

{%- liquid
  assign columns_mobile_int = section.settings.columns_mobile | plus: 0
  assign show_mobile_slider = false
  if section.settings.swipe_on_mobile and section.blocks.size > columns_mobile_int
    assign show_mobile_slider = true
  endif
-%}

  

    {%- unless section.settings.title == blank -%}
      

        ## 
          {{ section.settings.title }}
        
        {%- if section.settings.button_label != blank and show_mobile_slider -%}
          
            {{- section.settings.button_label | escape -}}
          
        {%- endif -%}
      

    {%- endunless -%}
    
    

      {%- if section.settings.button_label != blank -%}
        
          {{ section.settings.button_label | escape }}
        
      {%- endif -%}
