Allows to automatically show/hide dialog fields based on other fields values.

Supported Coral UI 3 components:

  • coral-select
  • coral-checkbox


  • Add the class wcmio-dialog-showhide to a select/dropdown or checkbox Granite UI component
  • Add a data attribute wcmio-dialog-showhide-target to the same element. The value should be a selector, usually a specific class name (the target class), to find all possible target elements that can be shown/hidden.
  • Add the target class to each target component that should be shown/hidden
  • Add the data attribute showhidetargetvalue to each target component, the value should equal the value of the select option that will unhide this element.
    • For select components use the select option value
    • For checkbox components use “true” or “false” for the checkbox state

To ensure the show/hide features is applied only to a certain group of elements in the edit dialog, when it cannot be ensured that the CSS class is unique across the whole dialog (e.g. in multi fields):

  • Add the data attribute wcmio-dialog-showhide-parent to the dropdown/select element, value should be a selector that identifies a common parent element. Only dialog fields that are children of that element (e.g. a container) will be processed.

This works the same as the AEM built-in cq-dialog-dropdown-showhide feature, but with additional features.
