Disable multiple selection
You can prevent users from applying actions to multiple items in a
      single right-click. In the accessrights.dtd file, you add
      the multiselect-disabled attribute to the file and then set
      the multiselect-disabled attribute to true for each menu option that you want to disable. 
When this attribute is set for a menu option, if a user selects multiple
            items and right-clicks to open the menu, the menu option will be disabled. If the
               hide-when-disabled attribute is also set to
               true for this menu option, then it will be
            hidden.
Note: Configuring this setting will
            override any default behavior.
         Note: You should make these configuration changes in the Test environment and test them before copying them to the Production environment. In a dedicated SaaS deployment, after testing the changes, ask IXIASOFT Customer Support to copy the changes to the Production environment.
