Conditionally show field based on another field?

Feature Request
1

The options docs for fields don’t make a reference to this, so I’m not sure if this is something already built into Cockpit.

Is there functionality already built into Cockpit that will conditionally show a field based on another field? For example, we create a collection of news items that can sometimes be external links. A boolean field in this collection called “external_link” is toggled on which then shows a hidden Text field for the url. When toggled off, the Text field is hidden.

No, that is not possible, unless you build your custom field or add some js in the middle.

But instead, why not build a repeater field combined with set, in way that you can choose the type of new item, e.g.:

https://monosnap.com/file/CMRemkOeYVig78VlZbbu957kBmOl7y

{
  "safeDelete": true,
  "fields": [
    {
      "type": "text",
      "label": "Simple Item"
    },
    {
      "type": "set",
      "label": "External Link",
      "options": {
        "fields": [
          {
            "type": "text",
            "label": "Text",
            "name": "text"
          },
          {
            "type": "text",
            "label": "Link",
            "name": "link"
          }
        ]
      }
    }
  ]
}

Beautiful solution! Thanks for the tip Paul, better approach than I’ve been going with

in the field options you can define a @visibility property, e.g:

"@visibility": "$.external_link === true"

This feature is experimental, that’s why it isn’t documented anywhere.
But feel free to try it out.

Hi @artur

Could this work within a set field? Either referencing a field in the set (example below) or a top-level field in the entry. Thanks

Hang

{
  "fields": [{
    "name": "first_name",
    "type": "text"
  }, {
    "name": "last_name",
    "info": "you need to provide your last name if you are John"
    "type": "text",
    "options": {
      "@visibility": "$.first_name === 'John'"
    }
  }]
}

@gnagnu sorry, unfortunately this doesn’t work for nested fields

Is this still working in the current version (v2.2.1). I tried on a text field, placing the line in the options field and even the meta > condition field with no success.
Can you provide an example of the whole options field?
