Groups are collections of items, often related to a specific region, subject, or project, that are created and managed by the group owner. If you have privileges to create groups, you decide who can find your groups, whether others can request to join, whether members can update items shared with the group, who can contribute content, and the type of items (for example, maps or layers) displayed by default in the group. You also have control over items shared with the group and can invite others to join, even if your group doesn't accept membership requests. Default administrators can also restrict who can see the list of group members and restrict members from leaving the group (administrative groups).
Organization administrators also use groups to configure the website with the organization's featured content (gallery page, home page, and basemaps) and configurable apps. If your organization is configured for Open Data, you can also make your public group available to open data sites.
Create a group
To create a group, complete the following steps:
- Verify that you are signed in and have privileges to create groups.
- Click Groups at the top of the site and click Create group on the My Groups tab.
- Add a thumbnail image to represent the group.
You can drag an image or browse to a file. For best results, add an image that is 400 by 400 pixels or larger with an aspect ratio of 1:1 in a web file format such as PNG, JPEG, or GIF. Pan and zoom to what you want to appear in your thumbnail. Depending on the size and resolution of your image file and how far you zoom in to customize the thumbnail, the image may be resampled and scaled when it's saved. If you add an image in GIF or JPEG format, it will be converted to PNG when it's saved.
- Provide a group name and tags. You can also add a short summary.
- For Who can view this group?, select one of the following:
- Only group members—Only members of the group can find and view the group. Members must be invited to join the group.
- People in the organization—Only members of the organization can find and view the group. Members can be invited to the group or apply to join.
- Everyone (public)—Anyone can find and view the group, even if they are not a member of the organization. This is the default.
Your sharing privileges may determine the options you can select. If you have a public account, the Everyone (public) option is the only option and can't be changed.
If your group will contain curated content to feature on your organization's Gallery page, select the option most appropriate for your intended audience. If you expect public visitors to view the gallery, select Everyone (public). Select People in the organization if you expect organization members to visit. Whether content items appear in the gallery also depends on how the items are shared.
- Select one of the following to specify who can join the group:
- Those who request membership and are approved by a group manager—Only members who request to join the group and are approved by the group owner or a group manager can join the group.
- Only those invited by a group manager—Only members who are invited by the group owner or a group manager can join the group.
Members of an enterprise group—Membership is controlled by an external enterprise group managed by a Security Assertion Markup Language 2.0 (SAML) identity provider (IDP). Each user's membership in the group is defined in the SAML assertion response received from the IDP every time the user successfully signs in.
This option is only available if the following conditions are met:
- You are an administrator with the privilege to link ArcGIS Online groups to SAML-based enterprise groups.
- An administrator has enabled SAML-based group membership for your organization.
To define the enterprise group, type the exact name (case insensitive) of the group in the text box.
The group name you enter must match the enterprise group name returned as the attribute value in the SAML assertion. If you aren't sure of the enterprise group name, contact the administrator who configured your organization's enterprise system.
- Anyone—Any organization member can join the group without being invited or approved. Members of other organizations can join the group as long as they have privileges to join external groups. Members who click Join this group on the group page are instantly granted membership in the group.
The options you see depend on the type of account you have (organizational or public), the option you selected in the previous step, and your privileges. If you have a public account, you can choose between Those who request membership and are approved by you and Only those invited by you. The Anyone option is not available for users with public accounts, as those users can't create (or join) groups with this option enabled.
- For Who can contribute content to the group?, select one of the following:
- Group members—All group members can contribute content to the group.
- Only group owner and managers—Only you (the group owner) and group managers can contribute content to the group. If you choose this option, members can view and access your items, but they can't share their own items with the group. This type of group is a good way to share your authoritative maps and data to a targeted audience. You control what items appear in the group and who can view them.
- For What items in the group can its members update?, select one of the following:
This setting is only available if you have privileges to create groups with update capabilities. Updates to an item include changes to the item details and updates to the content. This setting is only available when creating new groups and when membership in the group is only open to those who are invited or request and are approved to join.
- Only their own items—Group members can update only the items they own.
- All items (group membership is limited to the organization)—Group members can update any items shared with the group, which includes modifying the item details and updating the content. If you choose this option, the group becomes a shared update group, which limits group membership to members of your organization who have privileges to create, update, and delete content.
Only the owner (or administrator) of the item can perform the following actions on the item (not all actions apply to all item types): delete, share, move, change owner, change delete protection, publish, register an app, overwrite data in hosted feature layers, and manage tiles in hosted tile layers. However, members of this shared update group have other administrator types of privileges depending on the item type and the app used to access the item.
- For Who can see the list of members on the Members tab?, choose one of the following:
This setting is only available to default administrators. It is not available for SAML-based enterprise groups.
- All group members—All group members can see the list of group members.
- Only group owner and managers—Only the group owner and managers, and those with administrative privileges to view all members and groups, can see the full list of group members. Other members of the group will only see the group owner and group managers listed on the Members tab. Choose this option for public groups, such as community and crowdsourced groups, for which you want to protect the privacy of group members.
The item owner will still be displayed on the item page of individual items in the group. This option only applies to the Members tab of the group page. Organization members will be able to see the group as a filtering option when inviting members to a group or when managing members from the organization page Members tab.
- To change how the items are sorted on the group page, select a field from the drop-down menu.
For example, you can choose to sort by title, owner, view count, or date modified. To change how the items are ordered, check or uncheck the Ascending box. The sort field and order extend to your group when it is embedded in a website, shared as an app, and used to configure your organization's website (such as the basemap gallery). If you change the sort field or order, the item display is updated everywhere the group is used.
- Specify the type of items (for example, maps or layers) you want to display by default on the group's Content and Overview tabs.
- If you are a default administrator and want to restrict group members from leaving the group, check the box under Administrative group. If you check this box, group members can only leave the group if the group owner or a group manager removes them.
This setting is only available when creating new groups. It is not available for SAML-based enterprise groups or groups that allow users to join the group without being invited or approved. Only users in your organization can be members of a group with this setting enabled.
Only default administrators can own administrative groups.
- If you chose to make your group accessible to everyone (the public), and if your organization is configured for Open Data and you have the required privileges, check the Allow this group to be accessed in Open Data sites box to make your public group available to open data sites.
- Click Create group.
Your new group is created with the basic information and properties you specified. It is recommended that you add a brief summary about the group (if you have not already done so), as well as an in-depth description.
Your group is ready to be used. As the group owner, you can share items with the group using the Add items to group button on the group page. You can edit group properties on the Overview tab and group settings on the Settings tabs. Use the Invite users button on the Overview tab or the Members tab to search for and invite members to the group.
Edit group properties and settings
After creating a group, you, any group managers you designate, and administrators with group privileges can edit its properties and settings. For example, you can modify the group title or description, as well as change settings such as who can contribute content. For more information on working with groups you own, including managing group content and members, see Own groups.
- Verify that you are signed in as the owner, group manager, or administrator of the group you want to edit.
- Click Groups at the top of the site, and use the tabs, filters, sort options, and search as needed to find the group you want to edit.
- Click the name of the group to open its group page and do any of the following:
- On the Overview tab, click Edit next to the property you want to edit (for example, the description or tags), make your changes, and click Save to save your changes. You can edit the group name, summary, description, thumbnail, and tags.
- On the Settings tab, modify the group settings (for example, how group content is sorted, who can view the group, who can join the group, or who can contribute content). You can also specify the type of items (for example, maps or layers) you want to display by default on the group's Content and Overview tabs. When you're finished, click Save on the Settings tab.
Your ability to edit some settings depends on your privileges and group role. With existing groups, you cannot change the What items in the group can its members update? setting and the Administrative group setting that restricts members from leaving the group. These settings are only available for new groups. If you want to change any of these settings, you must delete the group and create a new one with the option you want.
Shared update groups
Organization administrators can create groups that allow members to update items that are shared with the group. These shared update groups are useful in collaborative situations in which multiple people need to update the same item—for example, shift workers in operations centers who need to update the maps underlying their apps and dashboards.
When members share an item with a shared update group, they remain the owner of the item. Other group members can update the item. Updates to an item include changes to the item details and updates to the content. For example, they can add layers to a map and save the map with the updated content.
To make your group a shared update group, select the All items option for the What items in the group can its members update? setting when creating the group.
At this time, shared update groups are intended for updating item details and the contents of maps, apps, and scenes. Some updates are reserved for the item owner or administrator (such as moving, sharing, or deleting an item and changing ownership). However, members of this group also have elevated privileges, such as the ability to edit the contents of hosted feature layers, alter editor tracking settings, enable or disable attachments, and alter the layer's schema. Therefore, proceed with caution when adding members to this type of group. Currently, most ArcGIS apps do not support updating items shared with a shared update group. To determine whether this capability is supported in a specific ArcGIS app, refer to its product documentation.
