If a group uses hashtags, you can view the list of hashtags using any of these methods:

• Desktop browser: On the group’s website, in the left menu, select Hashtags. The resulting Hashtags page lists all the hashtags that are used in the group. You can use the Gallery View and List View buttons at the upper right to change how the hashtags are displayed on the page.
• Mobile device: Tap the More icon at the bottom of a group page and then select Hashtags from the More menu.
• When you are viewing the group’s Topics page or Messages page, click or tap the Filter button at the top of the page, then click or tap the Hashtags button to display a dropdown list of the hashtags used in the group.

On the group’s Hashtags page or in the Hashtags dropdown list, you can click or tap an individual hashtag to display a page containing all the messages tagged with that hashtag.
