How can I do without splitting pane, when I use "ctrl+click" on side bar?

I want to select multiple files on side bar.But when I press “ctrl” and click the file with the mouse, it always split pane,which bothers me.How can I do without splitting pane?
I’m sorry for my poor English.

The split happens when a file is selected and it opens a preview; you can stop it from opening a split tab by setting this setting to false instead, though that will require you to double click files in the side bar in order to open them.

	// Preview file contents when clicking on a file in the side bar. Double
	// clicking or editing the preview will open the file and assign it a tab.
	// - true: Always preview on click, including right click
	// - false: Never preview
	// - "only_left": Only preview on left click, right click will change the
	//                selection but not preview the file.
	"preview_on_click": true,
