- You can use the ‘ClickedFcn’ callback rather than ‘valueChangedFcn’. This callback responds user whenever the user selects an option from the drop-down.
- You can use a ‘listbox’ instead of a ‘dropdown’ menu. The Listbox have ‘ClickedFcn’ callback function that can help you to achieve the same feature that you want.
Dropdown in AppDesigner Callingback when Selecting the Same Value

I intend to create a drop down with several options, and with each option being selected corresponding to a pop-up window.
{option1, option2, option3}
triggers respectively
{tab1, tab2, tab3}
I find by using "DropDownValueChanged" function there is a problem that, if I selected option1 last time and then select option1 again, it can't trigger anything. This is reasonable since it got triggered only when value is changed. However, is there a way that I can repeatedly select option1 to trigger tab1? That is, is there a callback like "value selected/ option pushed" that responses to user everytime when the user selects an item, instead of only when item selected is changed?

Hi
I understand that you want a callback function that responds to the user whenever the user selects an item in the dropdown.
