Support multiple image selections with default media library

[frankbits]

- { name: "img", label: "Image", widget: image, allow_multiple: true }

The allow_multiple-option of the image-widget seems to not be supported.
Or just the media-library does not support multiple-selection, which would make the option in line with the decap-cms-Doc

allow_multiple: (default: true) when set to false, multiple selection will be disabled even if the media library extension supports it

The allow_multiple option is only for external media libraries like Cloudinary and Uploadcare, which are not supported yet in Sveltia CMS. Well, I know there is an issue with Netlify/Decap CMS for supporting the option with the default media library. I’ll take care of it after adding support for external libraries and understanding the behaviour.

Let me clarify: it seems the allow_multiple option is for disabling multiple selections in an external media library. As the Decap CMS doc suggests, if you want to enable multiple selections in a media library, the configuration would look like this:

  - label: "Featured Image"
    name: "thumbnail"
    widget: "image"
    choose_url: true
    default: "/uploads/chocolate-dogecoin.jpg"
    media_library:
      config:
        multiple: true

Either way, this is not yet supported by the default media library both in Decap CMS and Sveltia CMS.

First thanks for your work!
i have try to implement a multi image, in decap is ok i can put more image, but sveltia ui can't do

Does it actually work in Decap? decaporg/decap-cms#6730 is closed as duplicate but is not fixed yet, I think. It should work in Decap if Cloudinary is configured as the media library, though there is a bug: decaporg/decap-cms#5812

sorry my bad, i have try fast with decap

backend: name: test-repo

and here the ui work good, but when use other backend we have the same problem

[kyoshino]

Ah the Test backend. I see.

I’ll work on this anyway, but multiple image selection is not recommended because generally each image should have an alt text for accessibility and SEO. You can instead use the List widget:

      - name: thumbnails
        label: Featured Images
        widget: list
        fields:
          - name: src
            label: Source
            widget: image
          - name: alt
            label: Alt Text
            widget: string
