As of my last knowledge update in September 2021, Facebook doesn't provide a built-in feature to share a post simultaneously to multiple groups directly from your personal profile. However, you can share a post to multiple groups manually, one at a time, by following these steps: *Using a Web Browser:* 1. *Log in to Facebook:* Open a web browser and go to the Facebook website (www.facebook.com). Log in to your Facebook account if you're not already logged in. 2. *Find the Post You Want to Share:* Navigate to the post you want to share on your News Feed or on the timeline of the user or page that created the post. 3. *Share the Post:* Below the post, click on the "Share" button. 4. *Choose the Sharing Options:* In the pop-up window that appears, you can: Add a caption or comment to the post if you wish. Choose where to share the post: click on "Share on Your Timeline" and select "Share in a Group." Begin typing the name of the group where you want to share the post, and Facebook will suggest groups from your list. Select the first group you want to share the post with. 5. *Share the Post in the First Group:* After selecting the first group, click the "Share" button to post the content in that group. 6. *Repeat for Additional Groups:* To share the same post to multiple groups, you'll need to repeat steps 3 to 5 for each additional group. 7. *Check and Confirm:* Double-check that the post is shared in each group as desired. Please note that manually sharing the same post to multiple groups can be time-consuming, especially if you want to share it to many groups. Also, make sure you follow the rules and guidelines of each group you're sharing to, as group administrators may have specific rules about sharing external content. Additionally, Facebook's features and interface may change over time, and new features or tools may have been introduced since my last update. If there are any changes or if Facebook has introduced a feature to simplify sharing to multiple groups, you can refer to Facebook's Help Center or the latest app updates for guidance.
