CMS: Allowing Visitors to Upload Multiple Media Files with the Upload Button
Important:Some functionality that allows you to test this feature in preview mode is not available to everyone. Use your live site to properly test uploading multiple media files with the Upload Button.Let your site visitors upload multiple media files at once (video and image files only), by adding the Upload Button to your page.For example, if your website is about art, you can accept multiple images from an artist. For a recipe-sharing website, visitors can upload entries that include multiple video clips of cooking.Using the Media Gallery field type in your collection, you can set up your website to accept and upload multiple media files at once.Note:Currently, you can upload multiple video or image files only. If you already have a page with an Upload Button in place, you can add a Media Gallery field to the collection and adjust the settings of your Upload Button:Show me how to set up an existing Upload Button to accept multiple media files

Wix Editor: Click CMS  on the left of the Editor. Editor X: Click CMS  at the top of Editor X.    Click Create Collection. Enter a name for the collection (this collection will hold the content that visitors enter). Click the How many items you want in your collection? drop-down and select Multiple items (Default). Click Create. In your new collection, use the Media Gallery field type for at least one field

 Close your collection.Step 2 | Add an Upload Button and a datasetYou can add an Upload Button and a linked dataset at the same time. It's easier to keep track of the collection you created in step 1 by adding the dataset in this step.New datasets experience: In Wix Studio, we've moved datasets to the Inspector panel on the right to make them easier for you to use. Learn more about the new datasets experience in Wix Studio. To add an Upload Button and a dataset:

Click the Upload Button, then click Settings. Click the Supported file type drop-down and select the file type you want the visitor to upload: Image & Video, Image, or Video. Set the Max number of files slider to the maximum amount of files you want visitors to be able to upload at a time.

Once a visitor selects a file, the file name is displayed.   Click View Uploaded Files to see files that have been uploaded by visitors.Step 4 | Add a Submit buttonThe Submit button is what your site visitors click on to upload their selected files to your site.
