Using Combined
Combined mode lets you combine multiple iStat Menus items into a single status item. You can choose which items are shown in the menu bar and which are shown in a combined dropdown, allowing you to save space in the menu bar while still having access to all the information in the dropdown.

Adding items #
To add an item to the Combined menu bar, simply drag it from Available Items to Menu bar Items. To add an item to the Combined dropdown menu, simply drag it from Available Items to Dropdown Items. It’s possible to have an item appear in the menu bar, dropdown menu or both. If you’d like it in both, add it to both! The items will appear in the order you arrange them.
Please note that items added to the Combined extra will only appear in the Combined extra (their normal item will be hidden). Also, the giant switch on the Combined tab needs to be turned on for the Combined to show, just like all the other extras.
Removing items #
To remove a menu bar or dropdown item from Combined, drag it from Items to show in Menu Bar or Items to show in dropdown to Available Items.
