Dashboard and Homepages sharing with sys_user dataSometimes you might want to restrict the users available when you share the dashboards. Be default, all the active users are available once you click on share --> users option. There is no direct way of restricting users per dashboard -- You can create ACLs / BR's on the sys_user table. But please note that these changes will affect other areas as well not just on one dashboard Please refer to the below product documentation on ACL's and BR's:Access Control RulesBusiness Rule -- Another workaround also refers to changes in sys_user table, Check through this property. "glide.cms.dashboards.sharing_with_secure_search"-- When enabled, the list of users, user groups, and roles that are visible in the sharing panel are restricted. The restriction is based on the configuration of the sys_user, sys_user_group, and sys_user_role ACLs. For more information, see Access control list rules.Note: There is a performance penalty associated with enabling this property. Performance degradation may be based on the number and complexity of business rules and ACLs in your instance.-- Please refer to the documentation below, for the same:Responsive Dashboards Properties
