How to cancel selection status on a menu?

I developed some mlapps in Appdesigner. I was confused that the selection status of menu would not cancel only if I clicked other positions. So everytime I clicked the first menu button, it turns blue and the coresoponding malpp will open.But If I moved my mouse by accident across other menu buttons, they will open,too. I just want to know how to sovle this or how can I canel the selection status of a menu button if I hav't click on other position.

I really want to know how to fix this,please help.

Is that TabGroup component?

I think it's a menu component. My matlab is shown in Chinese, I don't know how to change it into english. So I'm not sure.

It's a menu bar.

Will the bar turn back to normal when you close the opened mlapp?

But If I moved my mouse by accident across other menu buttons, they will open,too. I think that in general, when you press and hold the left mouse button, menus will open as you hover over them. When the mouse button is released, where the cursor is lastly located, that option will be selected if possible.

That's true. But maybe the sub program is a little big, so there is some time to open it. Then the selection status will be holding until sub program open.
