How can I add to the featured collection a subtitle that will also apear on the drawer customize?

Topic summary

A user wants to add a customizable subtitle field to a featured collection section that appears in the theme customizer’s drawer interface.

Solution Provided:

Extend the theme editor using Shopify’s {% schema %} tags by:

  • Locating the relevant section file in the theme code
  • Adding schema configuration between schema tags to create the subtitle field
  • This allows merchants to edit the subtitle directly through the theme customizer without touching code

Alternative Approach:

For those comfortable with coding, the subtitle can be hardcoded directly into the section file, bypassing the customizer interface.

An example schema structure for a slideshow section was shared to illustrate the syntax and format needed for adding customizable fields to the theme editor.

If you want to extend the theme editor this is done through shopify’s {% schema %} tags. This is a matter of going into the respective section and adding what you want between a set of schema tags. This is an example how a slideshow looks, and this would allow a merchant to add a slideshow through the theme editor. If you are comfortable with code though you can bypass this and add text directly in your code.

{% schema %}
{
  "name": "Slideshow",
  "tag": "section",
  "class": "slideshow",
  "settings": [
    {
      "type": "text",
      "id": "title",
      "label": "Slideshow"
    }
  ],
  "blocks": [
     {
       "name": "Slide",
       "type": "slide",
       "settings": [
         {
           "type": "image_picker",
           "id": "image",
           "label": "Image"
         }
       ]
     }
   ]
}
{% endschema %}
