Display all Default Modules Plugins Joomla Backend
In the Joomla backend, the default list limit is 20. If you have more than 20 plugins or modules on a page (including articles and menus), you are forced to page through the lists unless you change the display option at bottom.
There is a Global Setting to change the display of list items. Go to Site -> Control Panel and select Default List Limit value to 100. See below.
There is no option to display all by default, however you can edit the following configuration file to force this.
Go to /administrator/components/com_config/model/form/application.xml
